Hamburger

A hamburger (also called a beef burger, hamburger sandwich, burger or hamburg) is a sandwich consisting of one or more cooked patties of ground meat, usually beef, placed inside a sliced bun. Hamburgers are often served with lettuce, bacon, tomato, onion, pickles, cheese and condiments such as mustard, mayonnaise, ketchup, relish, and green chile.

The term "burger" can also be applied to the meat patty on its own, especially in the UK where the term "patty" is rarely used. The term may be prefixed with the type of meat used as in "turkey burger".
