  1. I was just given a zucchini that is 16″ long and 4″ wide and had no idea what to do with it! You have some great recipes that I will be trying out. We’re fortunate that “low-carb”, “lactose-free” and “gluten free” are of no concern or worry. It’s awesome that you took the time and effort to do this for those that are on low-carb diets. I will pass your site on to some family and friends who would benefit, though almost anyone can enjoy these recipes. I know my family will. Cheers!

  2. Oh, thank you, thank you Kalyn. I love zucchini and in addition to my go-to recipes, I sneak it into a lot of dishes. But this year I have 2 monsters that simply got away from me and I didn’t know what I was going to do with them. Your ideas look wonderful and innovative and I can’t wait to try them. Maybe I can make some of the recipes and freeze the results for this winter. 

  3. Oh, this Popeye eggs seem to be the right thing for me and my son. Since he ate his first vegetables, he loved Zucchine – now seven years later, they’re still one of his favorites. We use to make big batches of oven grilled long slices, so we can wrap pieces of feta in it or serve it with crispy baked potatoes, give them on a rocket salad or snack them pure.
    Your ideas sound delicious too, looking forward to try them. Thank you for the inspiration!

  4. Thank you! I had a monster that was hiding. It dwarfed my 12″ chef’s knife! Looking forward to trying the popeye eggs and maybe the “pizza” slices.

  5. Fantastic zucchini recipes, which I’ll definitely make use of. We grow a lot of zucchini, so thank you very much.
