Here’s a step up from your everyday tuna salad—leave out the mayo and replace with avocado, add some red onion, lemon zest and juice, sprinkle with the green of cilantro or parsley, and wow! Put it between two pieces of toast and you have a rather perfect tuna salad sandwich with the lovely addition of avocado and without any mayonnaise.

To be clear, I don’t have any problem with mayo. But I am rather passionate about avocados so given the opportunity to sub one for the other, I will!

By the way, here’s a cool little avocado beauty tip. Once you’ve scooped out the avocado from its peel, rub the inside of the peel on your elbows. The oil from the avocados is great for smoothing rough skin!

Avocado Tuna Salad Recipe

  • Prep time: 10 minutes
  • Yield: Makes enough tuna salad for 2 sandwiches

Since the avocado is taking the place of mayonnaise, it should be ripe and easy to mash with a fork. Choose an avocado that has some give to it when you squeeze it gently. Because mayonnaise comes salted, and avocados don't, you'll need to add more salt and pepper to this salad than you might expect.


  • 1 5-ounce can tuna, preferably packed in olive oil, drained
  • 1/2 ripe avocado, roughly chopped
  • 1/2 cup minced celery
  • 1/4 cup minced red onion
  • 1 Tbsp olive oil
  • 2 teaspoons lemon juice
  • 1 teaspoon lemon zest
  • 2 Tbsp chopped fresh cilantro or parsley
  • 1/2 teaspoon kosher salt
  • Freshly ground black pepper


Place all of the ingredients in a medium bowl. Mix with a fork, mashing the avocado and breaking up the chunks of tuna as you go, until the ingredients are well combined.

Add more oil or salt and pepper if necessary, serve on your favorite sandwich bread or toast.

    I added lime juice by mistake, but it was a really good mistake. This was delicious!

    Wow — this was delicious and so easy. The onion and lemon cut the fattiness of the avocado (which is sometimes too much for me). I omitted the celery because I didn’t have any and used some of the olive oil from the tuna can. So good!! I think it will be my go-to, high protein snack! Thank you for posting.

    So good! Not so heavy! It’s a keeper says my husband! Next time I’ll try with crab meat! :) Thanks for sharing!

    I made this salad for my lunch today. I didn’t add olive oil and I subbed green onions for the red (because I had them in my fridge). I put it on a bed of baby kale with tomato slices and a few chunks of fresh mozzarella cheese. I cannot wait for lunch time!!!
