How to Make a Tuna Melt?

Make your tuna salad the way you like it. Then, take some buttered bread, top the unbuttered side with a slice of cheese, some tuna salad, and a tomato, place another slice of buttered bread on top and broil until toasted, flip over and broil the other side. You could also grill the sandwich as though you were making a grilled cheese sandwich using a frying pan.
