Have you ever had a tomato pie? It’s a pizza that is mostly sauce, chunky sauce, but the sauce goes on top of the cheese. Some tomato pies, like the one I had today, don’t have any cheese. Just sauce.
The tomato pie seems to be a Trenton and Philadelphia food. Tomato pie is rare in other parts of New Jersey but around the Trenton area, it’s common.
Unlike typical New York-style pizza, which is closely related to Neapolitan pizza, tomato pie is derived heavily from Sicilian pizza, and as such can be found in predominantly Sicilian-American communities.Wikipedia
