These tuna buns are perfect for lunch or a sandwich supper. The tuna sandwiches are briefly baked, melting the cheese and making hot and satisfying buns.
In a bowl, combine the cheese, chopped eggs, tuna, green pepper, onion, olives, and relish. Add 1/2 cup of mayonnaise and stir to blend. Add more mayonnaise as needed to moisten.
Split and butter the hamburger buns. Divide the tuna mixture among the buns and wrap each one in foil.
Place the wrapped buns on a baking sheet and bake for 10 to 15 minutes, or until hot.
Notes
Make-Ahead: Refrigerate the buns until the oven is preheated and you're ready to bake (about 15 minutes before serving time).
