In the area I grew up in - the Hudson River Valley - we had tons of Italian and Polish deli's and restaurants. One place I loved was Rocky's. It was really a bar but they had great food. They'd cut a loaf of Italian bread in half, hollow it out, and fill it with meatballs and sauce, or pepperoni and sauce (my favorite). It was the size of a football and weighed a ton! A half was a "regular" sandwich! You couldn't eat it without getting sauce all over you. Man, it was good.
