Other vegetables, such as green pepper, tomatoes, mush rooms, and onions, may be added on the skewer. Add water and boil slowly for 30 minutes. Cool for 30 minutes and remove meat, reserving stock for basting. Preheat oven to 350 F. Stir tomato sauce into stock and empty it into a large baking dish. Place this under the rack at the center of oven.
Transfer roast onto the rack so that juices from the meat can drip into the dish underneath.
Continue baking at 350 F., allowing 1 hour per pound. Baste constantly with sea soned stock. Turn off oven and let roast stay in oven for 1 hour before serving. Add remaining ingredients and continue cooking slowly until water from gravy dries up and meat is tender. Add more water when necessary.
