French fries
Typical grill fare is available at grease trucks, but most popular are the "fat" sandwiches composed of permutations of various foods, such as burgers, French fries (in the sandwich), cheesesteak, mozzarella sticks, chicken fingers, pork rolls, marinara sauce, falafel, gyro meat, bacon, fried eggs, ketchup, mayonnaise, onions," etc." They supposedly originated in the 1970s when a local restaurant served a sandwich called the "Fat Cat" consisting of two cheeseburgers, French fries, lettuce, tomato, mayonnaise and ketchup, all combined, on a bun. In the 1980s, the Fat Cat became a popular item at grease trucks. The three other Fat sandwiches sold during the early history of grease trucks were the "Fat Moon" (chicken fingers, bacon, egg, french fries, lettuce, tomato, mayonnaise and ketchup), "Fat Koko" (pizza steak, french fries, mozzarella sticks), and "Fat Sam" (cheese steak, grilled chicken, french fries, lettuce, tomato, mayonnaise, and ketchup).
