I have to agree with Olivant 100% on that, it's was sauce for me growing up...All of my grandparents came from Italy, whether they cooked meat in the sauce or not i never heard them refer to it as gravy....One time i asked my grandfather about the sauce vs gravy question and this is what he said to me "Anybody asks for gravy in my house for their macaroni, I'm giving them just what they asked for - gravy - brown gravy! You want tomato sauce, you better ask for it!"... Now i'm not debating on what other people should call it, just giving my point of view.
