A Submarine Sandwich. The long sandwich featuring layers of meat and cheese on a crusty Italian roll goes by a variety of names. Submarine, sub, and hero are widespread. Localized terms are bomber (upstate New York), wedge (downstate New York), hoagie (Delaware Valley, including Philadelphia and southern New Jersey), grinder (New England), Cuban sandwich (Miami), Italian sandwich (Maine), Italian (southern Midwest), and poor boy (New Orleans, before Katrina) now goes by soggy boy.
Yeah, I'll have a Pepperoni, Italin Sausage, Ham and Salami Hero with everything on it.
