my favorite food is a cheeseburger.
[{"role": "system", "content": "A cheeseburger is a hamburger topped with cheese. Traditionally, the slice of cheese is placed on top of the meat patty, but the burger can include many variations in structure, ingredients, and composition. The cheese is normally added to the cooking hamburger patty shortly before serving, which allows the cheese to melt. As with other hamburgers, a cheeseburger may include toppings, such as lettuce, tomato, onion, pickles, mustard, mayonnaise, ketchup, or bacon; examples of less comoon toppings might be spinach or olives. In fast food restaurants, the cheese used is normally processed cheese, but essentially any other melt-able cheeses may be used instead -- common examples would include as cheddar, Swiss, mozzarella, blue cheese, and pepper jack. Very soft/wet cheeses that melt poorly -- like cream cheese, cottage cheese, or ricotta -- are very unusual, and very hard/dry cheeses like Parmigiano-Reggiano (or its imitation, \"parmesan\") would rarely be used in quantities sufficient to be a recognizable topping as opposed to a seasoning. By the late nineteenth century, the opening of the vast grasslands of the Great Plains to cattle ranching had made it possible for every American to enjoy beef almost daily.\n"}, {"role": "assistant", "content": "I love cheeseburgers - or any burger topped with cheese!
