Salt and pepper fish to taste. Use a heavy round pot with tight fitting lid, grease heavily with oil. Place a layer of seasoned fish chunks, covering the bottom of the pot. Cover with generous layer of chopped seasoning vegetables, half as thick as the fish layer; repeat, using all fish and vegetables, ending with vegetables on top. Cover tightly, place on low fire and cook 1 to 2 hours, shaking pot gently to loosen sticking fish. DO NOT STIR. Fish is done when vegetables are fully cooked, and liquid is about 1 inch above fish. Serve over cooked rice.
