There are a lot of salads with tomatoes and cucumbers on this blog and to me this combination just screams summer. But I also eat tomatoes and cucumbers all year round (whenever I can get delicious tomatoes or cherry tomatoes and Persian cucumbers from Costco.) So when a Hawaiian reader named Lisa sent me her recipe for that. Tomato, Cucumber and Avocado Salad Which she called “stupid salad” and said she was making it a lot, I cared about that.

Lisa discovered this combination when she was out of town and needed to use what was available, and I promise, this simple salad that combines cucumbers, tomatoes, green onions, avocado and balsamic vinegar is not stupid at all! This low-carb, keto, gluten-free, and vegan recipe will likely become a recipe you’ll make again and again when you have avocados and just want an easy salad for a side dish.

Of course, you only do it when you have delicious fresh tomatoes, but I loved the combination of flavors, with a little good sea salt and some coarsely ground black pepper. I also like the idea of ​​a salad with no added oil except for the “good fats” from the avocado. Lisa invited me to change it up a bit, but I didn’t really change it much except for the sliced ​​green onions for the sake of which she used sweet onions.

I was making more than I ate right away, so I also tossed the avocado with the tiniest bit of lemon juice to make sure it didn’t turn brown. Lisa’s friends suggested adding lots of chopped herbs, and I thought mint, basil or parsley could also have a supporting role in this salad if you wanted to add it, but I just made the salad as Lisa does and happily eaten it. for lunch!

What ingredients do you need for this recipe?

  • green onion
  • avocado
  • Fresh lemon juice, I used my own Fresh and frozen lemon juice
  • High quality balsamic vinegar
  • Sea salt and freshly ground black pepper to taste

What kind of balsamic vinegar did you use?

This simple salad contains so few ingredients that you want to make sure that every ingredient tastes great, so be sure to use good balsamic vinegar! But you don’t need the expensive $40 a bottle balsamic vinegar for this recipe! I’ve made it several times for an average price Colavita old balsamic vinegar (Referral link) I think it tastes great. Balsamic vinegar does color the other ingredients a bit, so if that happens white balsamic vinegar (affiliate link) which would also be a great option.

Tomato, Cucumber and Avocado Salad

How to make this salad:

(Scroll down for the full recipe including nutritional information.)

  1. I used this small Persian cucumber but you could also use a large European cucumber instead of the three small ones.
  2. I don’t have garden tomatoes yet, so I used sweet Cherub tomatoes from Costco. This is something I buy over and over again. (The carob never paid me or sent me tomatoes, I just love their product!)
  3. Slice the green onions to make about 1/4 cup, use more or less as desired.
  4. You need one fully ripe avocado, cut into small cubes.
  5. I tossed in the avocado with a few teaspoons of lemon juice to prevent the leftovers from turning brown, but I think 99% of the time you do this they will be eaten right away, so feel free to skip this step.
  6. Gently blend the cucumber, tomato, onion, and avocado together, then drizzle with enough high-quality balsamic vinegar to coat the vegetables.
  7. Season to taste with fine sea salt and freshly ground black pepper and enjoy!

  • 2 tsp. Fresh lemon juice (optional, for mixing avocado)
  • 1 ton high quality balsamic vinegar
  • Sea salt and freshly ground black pepper to taste


  1. Cut the cucumber in half lengthwise, then cut it into half-moon slices. (I never peel Persian cucumbers, but if you’re using another option, you may want to peel some of the peel in stripes before slicing.)
  2. Cut the tomatoes into cubes or cut the small tomatoes in half to make one cup. (Make this salad only when you have delicious fresh tomatoes.)
  3. Slice the green onions to make 1/4 cup or more if you like onions.

  5. Combine cucumber, tomato, onion and avocado in a plastic or glass bowl and mix gently.
  6. Add a small amount of balsamic vinegar, enough to just barely cover the vegetables, and stir again. (I used about a tablespoon of vinegar, which is a generous amount.)
  7. Season to taste with your favorite sea salt and plenty of freshly ground black pepper.
  8. If you love it as much as I do, you probably won’t have leftovers no matter how much you make!


You can also use one or two medium-sized European cucumbers in the garden.
