About Tuna Salad

There are so many, many variations of tuna salad. And we’ve tried quite a few. We also like this protein-packed tuna salad recipe version with boiled eggs.

The great thing about this recipe is that it’s budget-friendly. And we pretty much always have everything on hand.

But most of the time we go back to this version I created a few years ago.


How To Make A Sweet And Savory Tuna Salad Sandwich

  1. Peel and dice the red onion and the apple.
  2. Use a mixing bowl to combine the red onion, apple, tuna, sweet corn, and relish.
  3. Add mayonnaise and combine well. Season with salt and pepper.
  4. Toast a (gluten-free) bagel or sandwich bread. Put a generous layer of the tuna salad on the sandwich. Serve and enjoy.

Bonus Tip: If you want to cut down on calories, you can substitute Greek yogurt for the mayonnaise and it’ll still be yummy. And I’ve also made this recipe with 50/50 ratio of mayo and Greek yogurt. It works really well, too.

Tuna Salad Prep Tip:

Making the tuna salad right in the storage container saves on dirty dishes.

Just a quick prep tip. Instead of making the tuna salad in a classic mixing bowl and then putting it into a food storage container like this one, try making it directly in this Pyrex storage container with a lid.

This way you’ll simply pop a lid on and the leftovers directly into your fridge.
