This Avocado Tuna Salad is one of my favorite quick and easy lunches. And, I’ll let you in on a little secret — I’m not a huge fan of mayo. While I do like it in traditional Chicken Salad Sandwiches, I really avoid it everywhere else. So, I wanted to make a no mayo tuna salad because I knew avocado would be the perfect substitute, and it is! This organic tuna salad uses Safe Catch Tuna and organic veggies for a healthy Avocado Tuna Salad.

One of my neighbors brought me a huge bag of avocados and lemons from a family property in SoCal, so I’ve been making this no mayo tuna salad on repeat. You can enjoy this Avocado Tuna Salad all on its own. Or, you can also make a classic sandwich, top it with toast, or even dip crackers in for a light lunch.

Why You’ll Love This Recipe

No Mayo Tuna Salad: I’m not a huge fan of mayo, so this no mayo tuna salad has been on repeat for me! Avocados are also a much healthier addition to classic tuna salad than mayo.

Organic Tuna Salad: I’m using Safe Catch canned tuna as it’s one of the better options out there. While there is no organic canned tuna, you can still purchase Safe Catch for a better and more sustainable canned tuna option. I’m using all organic veggies and other ingredients in this Avocado Tuna Salad!

Healthy: I love this organic tuna salad because it’s so much healthier than the classic that’s made with mayo. This no mayo tuna salad is rich and creamy, thanks the avocado, and it’s even tastier than the classic.

Ingredients & Health Benefits

  • Tuna: I’m using Safe Catch canned tuna.
  • Avocado: Organic avocados are a healthy fat that’s also anti inflammatory. They have potassium, fiber, and more.
  • Cucumber: Organic cucumber has antioxidants and can help with digestion.
  • Red Onion: Organic red onions have antioxidants and anti inflammatory properties. This also gives this tuna salad a lot of flavor. I would not substitute for yellow or white onion as those can be more strong in flavor when raw and can be overwhelming.
  • Cilantro: I use a little organic cilantro which is anti inflammatory and loaded with vitamin A, C, K and more.
  • EVOO: I use organic regenerative extra virgin olive oil which is anti inflammatory and is a healthy fat.
  • Lemon Juice: You can use a fresh lemon or bottled organic lemon juice, either work. This adds a little acidity and flavor.
  • Mustard: I use organic yellow mustard for a little flavor and tang.
  • Seeds: I use my favorite Go Raw Organic Sprouted Everything Bagel Pumpkin and Sunflower Seeds as I’m obsessed with these. But, you can also use plain or salted seeds too. The seeds add a little more protein and give it a nice little crunch. Pumpkin seeds are also high in zinc and can help regulate hormones (which is why I eat them every day!).

FAQ’s

Can I use a white or yellow onion?

You can, but I wouldn’t recommend it unless you really enjoy the flavor of raw onions. These two onions can be much more strong when raw than red onion, which is why I prefer red onion here.

Can I make this ahead of time?

I wouldn’t recommend it as the avocado can brown. There is lemon juice in here which can help, but it still can happen. I recommend making this and then enjoying afterwards.

How can I store leftovers?

If you do have leftovers, you can store in an airtight container in the fridge. I also recommend placing a piece of plastic wrap directly on top of the salad, as this can help with browning if you wan to try that.
