A good tuna sandwich is one of the best lunches around: After all, canned tuna is low in fat and carbs, and high in protein. This Southern-style tuna is a deluxe version of the traditional tuna salad for sandwiches, which usually involves just mixing a little mayo with the fish.
Ingredients such as chopped hardboiled egg, sweet relish and diced celery add texture and flavor, while a creamy combo of mayo and Dijon mustard provides zip. For even stronger, tangier flavor, replace sweet relish with chopped dill pickle, or add extra Dijon mustard. Watching your carbs? Use leaf lettuce as a wrap for the tuna instead of bread or a roll. With no cooking time, it's ready for sandwiches, dips or lettuce rollups in a flash.
