Cut a 4 inch hole around the stem of the pumpkin. Remove the strings and seeds. Set aside. Sautee the onions in the oil. Add all other ingredients (except the pumpkin). Bring to boil and then simmer for 15 minutes. Spoon or pour the stew into the pumpkin as it sits on a shallow baking dish. Put the lid on the pumpkin. Coat the outside of the pumpkin with oil. Bake at 350 degrees for one hour. Let everyone admire the dish before peeling the pumpkin (just the thin outside skin), dishing out some stew and cutting up the flesh and adding to the stew.
This makes enough for 6-10 people depending on the size of the pumpkin.
