Keto Cucumber Avocado Tuna Salad

Alex Millet

Canned tuna is one of the most versatile foods when you're in a hurry and needs something high in protein, packed with healthy fats and super tasty. If you're looking for a great and easy recipe for dinner, this keto cucumber salad with avocado, tuna, cilantro, and lime is a wonderful choice.

The saltiness of the fish pairs perfectly with the creamy avocado to make a divine salad that doesn't feel like "rabbit food".



  • 1 avocado 
  • 1 tbsp fresh-squeezed lime juice
  • 1 large European cucumber (or 2 smaller cucumbers)
  • 1/2 cup chopped cilantro (more or less to taste)
  • 1/4 cup thinly sliced green onion
  • 1 can (5 oz.) tuna (either in water or olive oil)
  • salt and fresh-ground black pepper to taste 



  • 2 T mayo (can use light mayo, but there is not much mayo and full-fat mayo adds a lot of flavor)
  • 1 T fresh-squeezed lime juice (I used my fresh-frozen lime juice.)


  1. Dice the avocado into 1/2 inch pieces, put in a bowl large enough to hold the whole salad, and toss with one tablespoon of lime juice. 
  2. Peel strips from the cucumber if desired, then cut into fourths lengthwise and slice into bite-sized pieces.
  3. Chop the cilantro and thinly slice the green onion.
  4. Whisk together the mayo and lime juice to make the dressing.
  5. Add the chopped cucumbers, chopped cilantro, and sliced green onions to the avocado and gently combine.  Add the dressing and stir just enough to combine.
  6. Drain the tuna and use a fork to partly break apart the tuna into chunks.
  7. Stir tuna into the salad and GENTLY combine (don't over-stir; you want the tuna to remain chunky.)
  8. Season to taste with salt and fresh-ground black pepper and serve.  
This lasts okay if refrigerated, but it tastes much better freshly made.
