I'd like to know what the difference is between a ham and a ham sandwich.

A hamburger is a type of sandwich made from ground meat, such as beef or pork, that is cooked on a flat surface, usually a grill or frying pan. The meat is then placed between two slices of bread, which are then toasted or fried in butter or oil. Ham sandwiches are typically served cold and contain sliced boiled ham, sometimes with cheese, lettuce, tomato, and other ingredients.
