Preheat oven to 375o. Heat shortening or oil in a large skillet and brown chops on both sides. Sprinkle uncooked rice in bottom of a large baking pan, and sprinkle dry onion soup mix over rice. Place pork chops on top. If using canned soup, cover chops with undiluted soup and add enough water to pan to cover chops. If using homemade mushroom soup, pour over shops to cover. Bake uncovered for 1 hour.
