A cheese sandwich is a basic sandwich generally made with one or more varieties of cheese on any sort of bread, such as flat bread or wheat bread, that may also include spreads such as butter or mayonnaise.

Overview
Popular British sandwiches include the cheese and pickle sandwich, the cheese and tomato sandwich and the cheese and onion sandwich.

Another cheese sandwich is the limburger sandwich. Cooked meat can be added to cheese sandwiches, such as the ham and cheese sandwich and the bacon, egg and cheese sandwich.

Grilled cheese sandwich
Cheese sandwiches can be grilled or fried so that the bread toasts and the cheese melts (a dish referred to as a grilled cheese sandwich, or simply grilled cheese). A grilled cheese is often heated by placing the buttered slices of bread, with the cheese between the slices, on a frying pan or griddle. Another variation of a grilled cheese sandwich is to melt and fry cheese on the outside of the bread as well as melting the cheese inside the two slices of bread. When this is done, it produces a crunchy fried cheese exterior to the sandwich.

Another form of cooked cheese sandwich is the cheese toastie or toastie, a dish particularly popular in the United Kingdom that is prepared by either baking or grilling a cheese sandwich in an oven, or toasting bag in an electric toaster, or using a pie iron in order to toast the bread and melt the cheese. It is usually served as a snack, or as a (usually lunchtime) meal, in most cases with a side of salad.

The cheese dream, an open-faced grilled cheese sandwich, became popular in the U.S. during the Great Depression.

U.S. government cookbooks describe Navy cooks broiling "American cheese filling sandwiches" during World War II. Many versions of the grilled cheese sandwich can now be found on restaurant menus across the U.S. and internationally. In the United States, grilled cheese sandwiches are often served with soup (usually tomato soup), and may be served as a whole meal in the United States and other countries. This combination of grilled cheese and soup is referred to as a "comfort food."
