Add all ingredients to a sauce pot and simmer for at least 15 min on a medium to low temp. Stir frequently and consider using a breathable splatter guard to help prevent sauce splatters everywhere. The longer this cooks, the thicker it gets. If it gets too thick, you run the risk of a burned flavor in the sauce, so don’t over cook it.

When the sauce is heated through and the onions are cooked to your preference your sauce is ready to serve.
