In a large skillet, melt the butter and add the seasoned chicken breasts. Brown well, about 5 minutes each side. Remove and set aside. Add the mushrooms and saute about 5 minutes. Add the soups and the seasonings. Stir and bring to a low boil. Return chicken to skillet, cover and cook 45 minutes. Check seasonings and add if necessary. Add the milk at the end of cooking to thin the gravy. Serve over Wild Rice or just plain rice.
