A fat sandwich is a submarine-style sandwich variety that is characterized by being overstuffed with calorie-laden, fatty, fried ingredients such as gyro meat, chicken strips, fries, and mozzarella sticks. These supersized sandwiches originated at Rutgers University in New Brunswick, New Jersey, where they were originally served out of so-called Grease Trucks which were lined up on College Avenue, satiating the hunger of numerous students, mostly after a night of heavy drinking.
