Hamburger

A hamburger (also known simply as a burger) is a type of sandwich that consists of two buns, one or more meat patties (usually beef, but can be made from turkey, pork, or a combination of other meats), and is often garnished with cheese, onions, pickles, lettuce, tomatoes, and condiments such as ketchup or other sauces, mustard, and mayonnaise. The term hamburger can also apply to the meat patty itself.

The term hamburger originally derives from Hamburg, Germany, from where many people emigrated to the United States.

Louis' Lunch, in New Haven, Connecticut, is considered the birthplace of the American hamburger.
