Chinese dish, I call it cabbage and meatball soup at home. You can use boy choy instead of napa cabbage. This is a combination of a few variations to this recipe, and the way we like to eat ours. Serve with steaming hot rice for a complete meal. I like to place this in the crockpot (set-it-and-forget-it) and cook it for the afternoon if possible because the longer you cook this dish the more tender and melt-in-your-mouth the meatballs are.
