Coat Bottom Of Oven proof dish with a cooking spray (Pam), add the drained canned mushrooms (or fresh ones). Place the chicken on top of mushrooms and sprinkle the dry spaghetti sauce mix evenly over the top of the chicken. Then pour wine over the top of chicken>> wetting down the dry sauce mix. Add wine until you can just see it coming up around the chicken pieces (about 1 1/2 - 2 cups in a 10" x 10" baking pan). Loosely cover with foil (you want some steam to escape) and bake in a 350 oven for about 45 min or until chicken is done. This is a real simple, quick dish to fix. The sauce and wine make a kind of gravy so I usually serve it with buttered noodles.
