A grilled cheese sandwich is a hot sandwich made with one or more varieties of cheese (a cheese sandwich) on bread. It is typically prepared by heating cheese between slices of bread, with a cooking fat such as butter, on a frying pan, griddle, or sandwich toaster, until the bread browns and the cheese melts. Melt sandwiches are variations using additional ingredients, such as pepperoni, tuna salad, or ham. Grilled cheese is occasionally made by grilling. It is called a grilled cheese, despite the fact that it is obviously fried.
