Sauté onions until golden. Add celery and mushrooms. Set aside.

Cook rice with water and spices for 30 to 40 minutes or until done. Combine with vegetables.

Stuff the chicken (under the skin) with rice mixture, folding under the skin edges. Place in a nine- by 13-inch pan very close together.

Brush on oil and sprinkle with more garlic powder and paprika.

Bake, covered, for two hours at 350 degrees Fahrenheit. Uncover; pour duck sauce over chicken and bake another 20 minutes.
