As Judge John Hodgman would say, the "is a hot dog a sandwich" debate is settled law. Still the debate rages on, with Stooch siding with precedent. His logic, however, that a sandwich must involve two slices of bread ignores such sandwich staples as the hoagie/sub/grinder and the cheesesteak. However, as he is from the UK, I think we must allow for the cultural gastronomic gap.
