Hamburger

A hamburger, also called a burger, is a dish consisting of fillings—usually a patty of ground meat, typically beef—placed inside a sliced bun or bread roll. The patties are often served with cheese, lettuce, tomato, onion, pickles, bacon or chilis with condiments such as ketchup, mustard, mayonnaise, relish or a "special sauce", often a variation of Thousand Island dressing and are frequently placed on sesame seed buns. A hamburger patty topped with cheese is called a cheeseburger. Hamburgers are typically associated with fast-food restaurants and diners, but are also sold at various other restaurants. There are numerous international and regional variations of hamburger. Some of the largest multinational fast-food chains have a burger as one of their core products: McDonald's Big Mac and Burger King's Whopper have become global icons of American culture.
