Drain beans in a colander and set aside. Place allspice, peppercorns, and whole cloves in a spice mill or blender. Process until coarsely ground. Brown the sausage in a six to eight quart sauce pan or large skillet. Crumble the sausage with a spoon or spatula as it is cooking. Do not drain. See note below Saut� the bell pepper and onion with the browned, crumbled sausage until the onion is just starting to become translucent. Stir in the drained beans and bbq sauce. Heat until it begins to bubble, stirring occasionally. Stir in spice mixture and brown sugar. Reduce heat and simmer for fifteen minutes. Meanwhile, preheat oven to 375 degrees. Transfer beans to a suitable, oven proof serving dish. Bake, uncovered, in oven for thirty minutes. Serve hot from the oven or allow to cool as desired. Note: If a sausage other than Jimmy Dean is used there may be an excess amount of fat. This fat will continue to render as the beans cook, and may result in a greasy dish of beans! If you must substitute, do so carefully and drain off the excess fat.
