Using a fork, mix all the ingredients, except the ketchup and pepper rings. Shape into a loaf and put into greased crockpot. Top with ketchup and pepper rings. Cover and cook on high for 1 hour, then on low 6 to 8 hours. Quartered potatoes coated with butter may also be cooked with this recipe. A dash of Paprika will give them a nice browned look.
