Simmer, covered, one hour, stirring occasionally. Simmer another hour uncovered. (Discard bay leaf when sauce is finished.)

For spaghetti sauce: Add cooked ground beef (and meatballs!) along with other vegetables, sauteed with the beef, as desired–peppers, mushrooms, etc. (Amounts depending on how much sauce you’re using for spaghetti.)

Also use for pizza sauce, and for a base sauce to shortcut lasagna. Simply add the cooked sausage and ground beef.

To store: Use a ladle or large scoop (a measuring cup works good) and place in freezer bags.
