The original fat sandwich – called the Fat Cat – dates back to the 1970s and was made up of a double cheeseburger, fries, lettuce, tomato, mayonnaise and ketchup. These days, R U Hungry? is one of few original fat sandwich spots left from the 1970s and, although it now operates from a restaurant instead of a grease truck, it remains the go-to place to try the dish in New Brunswick. Here you can feast on dishes like the Fat Freddo, which is stuffed with chicken fingers, mozzarella sticks, turkey bacon, chilli, cheese sauce, French fries and hot sauce. Other popular spots to grab a fat sandwich include PJ's Grill & Pizza and Adrian's Jersey Pizza, both of which serve all kinds of creative versions.
