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 the tuna salad with 50/50 ratio of mayo and Greek yogurt. It works really well, too.

At the end of the day it’s really your own preference that counts. But if you’re like us and like to splurge now and then, you’ll enjoy the tuna salad with mayo.

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 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.
