A hamburger (also burguer for short) is a sandwich consisting of one or more cooked patties of ground meat, usually beef,
placed inside a sliced bread roll or bun. The patty may be pan fried, grilled, smoked or flame broiled. Hamburgers are
often served with cheese, lettuce, tomato, onion, pickles, bacon, or chiles; 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 topped with cheese is called a cheeseburger.
