2 lb. very lean ground beef
1 jar of your favorite spaghetti sauce or homemade

Shape beef in patties a bit thicker than your usual hamburger; meat will puff up in cooking. Place 1 layer in bottom of pot. Top with a layer of sauce. Place a second layer of patties. Add more sauce. Continue doing this until all patties and sauce are in the pot. Cook on low for 8 hours.
