The HEALTHIEST Tuna Salad Sandwich | Packed with GOODNESS & Easy to Make

This tuna sandwich is possibly the HEALTHIEST Tuna Salad Sandwich Ever. We’re talking layers of flavors, simple heart-healthy ingredients, and all done in about 10 minutes. Serve it next to some roasted potatoes and a garden salad for an incredible lunch or dinner.

The HEALTHIEST Tuna Salad Sandwich
What makes this tuna salad sandwich healthier than the rest is using low-fat Greek yogurt instead of mayonnaise. This gives it that creamy goodness but without sacrificing flavor. As for the tuna, I used canned tuna in olive oil. You can also use canned tuna in water if you prefer.

For the bread, I used whole wheat sandwich bread. You can use whatever type of bread you like. The most important thing is to make sure you lightly toast the bread. That way, once you add the tuna salad, it doesn’t get mushy and break apart.
