*If you decide to make meatballs, leave out the ground meat in the directions above. Add two tablespoons of olive oil to the pot and sauté the onions for about 4-5 minutes and proceed with step two. You can either cook the meatballs in the sauce (add them into the simmering sauce raw), or bake them, and add them in when you add the balsamic to allow them to heat through in the sauce.
**When simmering, I leave the lid partially on, or off with a splatter screen.
