In a large skillet, brown chicken in butter. Transfer to a greased 13 in x 9 in x 2 in baking dish. In the drippings, sauté apples, onions, and mushrooms until apples are crisp-tender.

Add flour, soup, water, cumin, Worcestershire sauce, salt and pepper, mix well. Pour over chicken.

Cover and bake at 350 for 1 hour or until chicken juices run clear. Sprinkle with chili powder. Serve with rice.
