Avocado Tuna Cucumber Salad Recipe

This salad is very similar to my favorite Tuna Cucumber Salad, but with added avocado and flavorful red onions.

Loaded with healthy fats and protein, this avocado tuna salad is extremely easy to make with just a few simple ingredients, that you may already have on hand.

The ingredients pair very well together for a tasty and chunky salad, that could be served over toast to make a sandwich, on a bed of lettuce or to  make a wrap sandwich with it. It is kids and adults favorite around here. These are three of our favorite ingredients – cucumbers, avocado and tuna.

Here comes an important question – is this tuna salad healthy? Not all tuna salads are healthy, it all depends on the ingredients and amounts used in the recipe. But this cucumber avocado tuna salad is definitely on the healthier side. There is no mayonnaise used in the dressing, which makes it lighter. We use avocado instead of mayo, it is made with wholesome ingredients and rich on omega 3 fatty acids and protein.

How to make this easy and nutritious Tuna Avocado Cucumber Salad ?

All you need to do in order to make this salad is gather all of your ingredients, cut the cucumber, dill (optional) and avocado, drain the fish, and combine in a bowl. Add the dressing ingredients and stir to combine. Serve.

Ingredients:

  • 2 large cucumbers, peeled and chopped

  • 1 large avocado, peeled, pitted and chopped into small pieces
  • 8 oz canned tuna in olive oil
  • 1/4 red onion, chopped
  • 1-2 tbsp chopped fresh dill (optional)
  • 1/4 tsp salt or more to taste
  • 1/8 tsp ground black pepper
  • 2 tbsp apple cider vinegar or lemon juice (more or less to taste)
  • 2-3 tbsp olive oil

Directions:

  • In a large bowl combine the cucumbers, avocado, dill and flaked fish.
  • You can combine the salt, pepper, lemon juice (vinegar), olive oil and oregano in a bowl. Drizzle over the salad, then toss to combine.

Recipe tips:

  • Pick your ingredients wisely – choose English or Persian cucumbers, because they tend to have fewer seeds and crunchier texture. Make sure the avocados are nice and ripe. Choose a good quality canned tuna fish, if possible.
  • Tuna in water – I usually use canned tuna in olive oil in recipes like this, but at times I prefer to lighten up my tuna salad. For that reason, canned tuna in water can be used. 
  • Storing this salad – keep in an air tight container in the fridge for up to 1 day. The ingredients in this salad don’t store well for longer time, because the avocado may brown, despite it is covered with the dressing and cucumbers may get soft and soggy. Of course you may store the salad in the fridge for a few more days, if you decide to.
  • Salad add ins – you can certainly add some ingredients to the salad to adjust it to your taste. Add some canned corn, roasted red peppers, olives, capers to enhance the nutritional value of the salad. Fresh parsley, coriander or thyme, hot pepper flakes, sumac or any herbs of your choice can be sprinkled on top of the salad.
  • Is this tuna avocado salad Keto? – Yes! It is Keto. Serve it with my favorite Keto Bread to make a delicious low carb sandwich.
