Crockpot Italian Chicken

1 cabbage, small, cut in wedges
1 8-ounce can mushrooms, canned
2 tablespoons tapioca, quick cooking
6 chicken breasts, frozen*
1 jar spaghetti sauce, meatless
1 Parmesan cheese, grated

*Remove skin and buy boneless breasts - frozen works well in crockpot.
In a 3 1/2 to 6 quart crockpot place cabbage wedges, onion and mushrooms. Sprinkle tapioca over vegetables. Place FROZEN chicken pieces atop vegetables. Pour spaghetti sauce over chicken. Cover; cook on LOW for 8-10 hours. Transfer to a serving platter. Sprinkle with Parmesan Cheese.
