OP, no meat, but browned chopped onions and garlic, finely chopped carrot, maybe chopped mushrooms, and whatever other vegies you love. Tomato sauce like a jar of Dolmio/raguletto/etc, plus a tin of crushed tomatoes, or (and definitely my preference) a bottle of chunky tomato sauce (since I don't make my own, I find the safeway homebrand in the tall bottles the best, it's not just puree.). Carefully stir in the browned meatballs, cover and simmer gently (stirring occasionally) until the meatballs and vegies are cooked. Serve with pasta/spaghetti. Very easy, and just add herbs if you choose, and a little beef stock powder before it all simmers.
