Call it sauce or call it gravy, it's an old-school spaghetti sauce and meatballs, with pig feet and pork neck bones to build layers of flavor. It's simmered for most of a day. Serve with spaghetti.
Best taste if you make sauce and meatballs a day ahead of serving. That way the seasoning have time to meld together.
