my favorite food is a burger.
[{"role": "system", "content": "A hamburger, beefburger or burger 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, barbecued, or flame broiled. Hamburgers are often served with cheese, lettuce, tomato, bacon, onion, pickles, or chiles; condiments such as mustard, mayonnaise, ketchup, relish, or \"special sauce\"; and are frequently placed on sesame seed buns. A hamburger topped with cheese is called a cheeseburger. 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, or the term can even refer simply to ground beef. The term may be prefixed with the type of meat or meat substitute used, as in \"turkey burger\", \"bison burger\", or \"veggie burger\". Hamburgers are sold at fast-food restaurants, diners, and specialty and high-end restaurants (where burgers may sell for several times the cost of a fast-food burger, but may be one of the cheaper options on the menu). There are many international and regional variations of the hamburger. The term \"hamburger\" originally derives from Hamburg, Germany's second-largest city. In German, \"Burg\" means \"castle\", \"fortified settlement\" or \"fortified refuge\" and is a widespread component of place names.\n"}, {"role": "user", "content": "I love a good hamburger, I even a not so good once in a while."}, {"role": "assistant", "content": "The modern hamburger was created because of rapidly changing society due to industrialization.
