Heat the oil in a large, heavy pot over high heat and lightly brown the roast on all sides. Add the remaining ingredients and bake covered in a 300F (150C) oven for 3 to 4 hours, or until meat is tender. You may also simmer it covered on the stove over low heat for 3 to 4 hours. Under either method, check the pot occasionally and add more liquid if necessary.
Remove the meat when it is done and cut into thick slices. Arrange the sliced meat on a serving platter or individual plates and add the vegetables. Discard the onion and bay leaves. Skim the excess fat off and ladle the remaining liquid over the meat and vegetables. Serves 4 to 6.
