I was born in Pennsylvania, spent some of my childhood there, and we always called them submarine sandwiches. When I lived in Texas for awhile they called them hoagies. My husband from MA calls them grinders. To me, a hoagie has mayo and is just like a sandwich on a sandwich roll. A submarine has Italian dressings like with thin onions and other veggies. Coming back from Europe that was one of the first things I would always want!
