Illinois is most famous for deep-dish pizza, Italian beef sandwiches and Chicago-style hot dogs. These foods all originated from Chicago, a city famous for its food.
Deep-dish pizza is baked in a deep, round pan and covered with a thick layer of tomato sauce, cheese and a variety of other toppings.
Italian beef sandwiches are made with thin slices of seasoned roast beef, served in a long Italian roll, and dipped in the juice from the cooked beef.
A Chicago-style hot dog consists of an all-beef hot dog on a steamed poppy seed bun, topped with yellow mustard, tomatoes, onions, pickle spear, hot peppers and celery salt.
