This is the chili I remember eating as a child before microwaves were invented. This can be made in the microwave in about 30 min. but I prefer making it on the stove and then simmering it for an hour or so. The oregano is optional, I myself do not use it. Serve what you need then freeze the rest. For quick defrosting and heating, divide into single servings and package in shallow freezer boxes or heat seal-able bags.
