The traditional grinder is similar to the classic hoagie and contains the same central ingredients. The variation is that these sandwiches are often topped with roasted red peppers or adorned with mayonnaise. A hot grinder is made on the same type of roll with ingredients such as meatballs, Italian sausage, red sauce, peppers and melted cheese.

Cursory online research will tell you that each of these names has a distinct origin, with "hoagie" referring to a type of sandwich that was popular among Italian workers on Hog Island in Pennsylvania (get it?); "grinder" a slang term for dockworkers who were fans of a similarly structured sandwich; and the "sub" being a broad descriptor for any long, spherical sandwich that resembles a submarine.
