Tuna salad has long been a lunchtime staple, beloved for its simplicity, versatility, and satisfying protein punch.

Tuna melt casserole is far superior to those old tuna casseroles from your childhood. It nods to the classics with a topping of cheese and tomato slices, but it's much more balanced and special.

Tuna salad is the base for so many great and easy meals, from sandwiches to dip to, well, salad, but what if you need to swap out the mayo? Use this instead.
