Not-so-Dumb Salad with Cucumber, Tomato, and Avocado

Not-so-Dumb Salad with Cucumber, Tomato, and Avocado is an amazing recipe I got from a reader named Lisa and the simple dressing of just balsamic vinegar makes these ingredients shine!

There are a lot of salads with tomatoes and cucumbers on this blog. To me that combination just screams summer, but I also eat tomatoes and cucumbers all year (whenever I can get good flavorful tomatoes and Persian cucumbers from Costco.)  So when a reader from Hawaii named Lisa sent me her recipe that she called “dumb salad” and said it was something she made often, I was interested. Lisa discovered this combination when she was going out of town and needed to use what was on hand, and I promise you, this salad idea that combines cucumbers, tomatoes, green onion, avocado, and balsamic vinegar is not dumb at all!  

That’s why I had to re-name it Not-so-Dumb Salad with Cucumber, Tomato, and Avocado! Of course, only make this when you have fresh flavorful tomatoes, but I loved the combination of flavors, accented with just a little good sea salt and some coarse ground black pepper.  And I also love the idea of a salad with no added oil except the “good fat” from the avocado.

Lisa invited me to change it up a bit, but really I didn’t change it much except to sub diagonally-sliced green onions for the sweet onions she used.  I was making more than I’d eat right away, so I also tossed the avocado with just the tiniest bit of lemon juice to make sure it didn’t go brown.  Lisa’s friends suggested adding lots of chopped herbs, and I’m thinking mint, basil, or parsley could also have a supporting role in this salad if you wanted to add them, but for my first time I just made the salad like Lisa does and happily gobbled it up for lunch!

How to Make Not-so-Dumb Salad with Cucumber, Tomato, and Avocado:

(Scroll down for complete recipe including nutritional information.)

  1. I used those small Persian cucumbers but you could also use one large European cucumber instead of three small ones.
  2. I don’t have garden tomatoes yet, so I used sweet Cherubs tomatoes from Costco.  This is something I buy over and over.  (Cherubs has never paid me or sent tomatoes, I just like their product!)
  3. I cut the green onion in diagonal slices to make about 1/4 cup, use more or less to taste.
  4. You need one perfectly ripe avocado, diced into smallish pieces.
  5. I tossed the avocado with just a couple of teaspoons of lemon juice to keep the leftovers from turning brown, but I’m guessing 99% of the time you make this it will all be eaten right away, so feel free to skip this step if that’s the case.
  6. Gently toss together the cucumbers, tomatoes, onion, and avocado, then dress with just enough good quality balsamic vinegar to coat the veggies. 
  7. Season to taste with good sea salt and fresh ground black pepper and enjoy!

Not-so-Dumb Salad with Cucumber, Tomato, and Avocado

Yield 2 generous servings
Prep Time 20 minutes
Total Time 20 minutes

This simple and delicious salad I got from a reader named Lisa just has cucumbers, tomatoes, avocado, green onion, and balsamic vinegar, and this is definitely not a dumb idea for a tasty salad!


  • 3 small Persian cucumbers (see notes)
  • 1 cup diced tomato or cherry tomatoes
  • 1/4 cup thinly diagonally sliced green onion
  • 1 avocado
  • 2 tsp. fresh lemon juice (optional, for tossing with avocado)
  • 1 T good-quality balsamic vinegar
  • sea salt and fresh ground black pepper to taste


  1. Cut cucumbers in half lengthwise, then slice into half-moon slices.  (I never peel Persian cucumbers, but if you use other cucumbers you might want to peel some of the skin off in stripes before you slice them.)
  2. Dice tomatoes or cut cherry tomatoes in half to make one cup.  (Only make this salad when you have flavorful fresh tomatoes.)
  3. Diagonally slice green onion or slice onion to make 1/4 cup, or more if you like onion.
  4. Peel and cut up the avocado into small cubes.
  5. Combine the cucumber, tomato, onion, and avocado in a plastic or glass bowl and gently toss together.
  6. Add a small amount of balsamic vinegar, enough to barely coat the veggies, and toss again.  (I used about a tablespoon of vinegar, which was plenty.)
  7. Season to taste with your favorite sea salt and plenty of fresh-ground black pepper.
  8. If you’re making more salad than is going to be eaten right away you can toss the avocado with a few teaspoons of fresh lemon juice so they don’t turn brown, but this is best freshly made.
  9. If you like it as much as I did, you probably won’t have leftovers no matter how much you make!


You can also use one large European cucumber or two middle-sized garden cucumbers.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
This Salad with Cucumbers, Tomatoes, Onions, Avocado, and Balsamic Vinegar is perfect for most types of low-carb eating plans, including Paleo. Everything in this salad is a perfect low-glycemic and low-carb ingredient for the original South Beach Diet. Avocado is a limited food for South Beach, so keep that in mind. This recipe does have some carbs in the tomatoes and avocado, but there is also fiber so the net carbs are lower than you might think. If you want a lower-carb option, use more cucumber in proportion to the tomato and avocado.

  1. I'm eating this right now – Delicious! And sooo easy to make! It's been a couple weeks since I've bought processed food at the grocery store – I have been so hooked on making recipes from your blog. My grocery bill, needless to say, has been much less, and my eating much healthier. 🙂

  2. Love this recipe, so simple but so delish! Am eating it for lunch right now in fact.

  3. I started South Beach this week, and this was one of the first new recipes I tried to keep myself excited about changing my eating. It was SO, SO, SO good! I'm not a big avocado fan, but loved it with the balsamic. Yum!!!

  4. This salad is great. Your Top Ten Recipes of 2011 post reminded me that I've never left a comment. I made this salad in the summer with my own tomatoes. You are (of course) right that you need a top balsamic vinegar for this. Quality balsamic vinegars tend to be sweeter. There is, however, a trick I sometimes use when I just cook for myself and I don't want to use my gourmet balsamic vinegar: I just use a less expensive balsamic vinegar (one that I have around for everyday salads) and add a bit of sweetener.

  5. Glad people are trying this and liking it, and yes I think the variations are infinite!

  6. The cucumbers are rampant abundant and the tomatoes are just starting to appear at my local farmers markets…looking for new recipes to enjoy the bounty, different types of vinegars can change the flavors from day to day.

  7. Yum!
    I make a similar salad adding Basil and or Chives. LOVE those summer herbs. I've also added a little quinoa from time to time.
    I'll be making a lot of cucumber salads soon as the garden is cruising along!!
    Photos look delicious! Thanks!

  8. Not so dumb at all! I can't wait to try this. So interesting there's no oil, except from the avocado. 😉

  9. Beautiful salad…and light for the summer.

  10. Lady Amalthea, that's just what made this salad so delicious; I loved it too.

    Judith, so glad you're enjoying the recipes.

    Sam, that's great news! It's such a good feeling when you get on the scale and see some progress. I think I could eat tomatoes and cucumbers together at least once a day and never get tired of them.

  11. We are trying to lose weight and have been eating sort of South Beach style serving a lot of tomatoes and cucumbers. My husband got on the scale this morning and was the lowest he's been in years and was thrilled. When he told me, I replied, "Must be the tomatoes and cucumbers," and I really do believe that's a big part of it.

    Thanks for this recipe. Love that it doesn't have oil. Will definitely give it a try.

  12. Kalyn: i so enjoy your blog and have tried several recipes. Last nite I made shrimp and grits which is delicious but very rich. Your wonderful smart salad was the perfect foil – clean, crisp and utterly delicious. Thanks so much for the recipe.

  13. Brilliant! I really love the idea of using the fat from the avocado to "replace" that from olive oil. All kinds of fun ideas are popping up now …

  14. Thanks Maggie, and I do highly recommend the salad!

  15. This looks wonderful! Sometimes simple, seasonal recipes are the best. I just came across your site via tastespotting, and I'll definitely be back!

  16. Just so glad people are liking this so much, because it really was spectacular. I'm going out to look for cucumbers right now and if I find some I'm making it again tonight!

  17. The color got me – so vibrant! Love anything with avocado and tomatoes. Not sure why I don't incorporate cucs in my diet more. Maybe if I lived next door to your garden…:)
