PIN Tuna Avocado Tomato Salad to try it later!

When it’s really hot outside, nothing tastes better to me than a main-dish salad like this Tuna Avocado Tomato Salad. This is a salad that started as a lunch inspired by the need to use up some cilantro, but once I added juicy cherry tomatoes, avocado, Italian tuna, and and a dressing with lime juice and it turned out to be a salad recipe I’m sure I’ll be making over and over.

And if you’re growing cherry tomatoes and having a cherry tomato explosion at your house, this salad is an easy and delicious way to use them. And it’s also just as tasty with cherry tomatoes from the store!

What ingredients do you need for this recipe?

• avocado
• fresh squeezed lime juice (I used my  fresh-frozen lime juice)
• cherry tomatoes
• chopped cilantro (see notes)
• sliced green onion
• Genova Tuna Packed in Olive Oil (affiliate link), or other tuna of your choice
• fresh ground black pepper
• Olive Oil (affiliate link), preferably extra-virgin olive oil

What canned tuna do I like best?

I used my favorite Genova Tuna Packed in Olive Oil for this recipe, which is probably one of the reasons this tasted so good to me. This is the brand I buy over and over and it’s much less expensive than the imported olive oil packed tuna I used to buy. I’ve used this tuna in so many salads and I never got tired of eating it.

What makes this recipe low in carbs?

This salad is very low in net carbs, partly because I use a generous amount of tuna in proportion to the other ingredients.

What if you’re not a fan of cilantro?

I realize cilantro is a deal-breaker ingredients for some people, and if you have those anti-cilantro tastebuds just use more thinly-sliced green onion and skip the cilantro.

Notes

If you substitute larger diced tomatoes, I would drain them in a colander. I love Genova Tuna Packed in Olive Oil (affiliate link), but use any tuna you like for this salad. Measure the cilantro after chopping; use a more green onion and leave out the cilantro if you're not a cilantro fan.

I would use my fresh-frozen lime juice for this recipe. I like sour flavors, but you might want to use less lime juice if you’re not a huge fan of lime.
