A cheese sandwich is a sandwich made with cheese on bread. Typically semi-hard cheeses are used for the filling, such as Cheddar, Red Leicester, or Double Gloucester. A Guardian article called the cheese sandwich a "British lunchtime staple". Using a sandwich toaster or frying pan can transform the cheese sandwich into a cheese toastie. When a meat sandwich is prepared, the cheese becomes the accompaniment, and the sandwich is known by other names such as ham sandwich, tuna sandwich, etc. If the cheese is melted on such a sandwich, the term melt sandwich is used.
