Wikipedia: Grilled cheese
A grilled cheese (sometimes known as a toasted sandwich or cheese toastie) is a hot sandwich typically prepared by heating one or more slices of 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.
