Slice onions thin; brown with chops in the fat. Arrange in large baking dish. Peel and dice apples. Place on top of chops. Sprinkle with salt, pepper and cinnamon. Blend flour with 1 cup bouillon or stock; add remaining bouillon. Cook, stirring constantly, until thickened. Pour over chops and apples. Cover, bake at 350° for 2 hours. Top with hot mashed potatoes. Drizzle with melted butter; return to oven long enough to brown potatoes slightly.
