  1. Combine chicken and mushrooms in a 3-1/2 – 4 quart slow cooker.
  2. Stir together pasta sauce, broth, sherry (if desired), nutmeg, parsley, red pepper, and pepper in a separate bowl. Pour over mixture in crock.
  3. Cover. Cook on Low for 5 to 6 hours or on High for 2 1/2 to 3 hours. Follow directions on the package of spaghetti; drain.
  4. Stir cheese into chicken mixture.
  5. Serve over hot cooked spaghetti.

Sprinkle each serving with green onion and also delicious with a loaf of warm bread.

I only have a 6qt. crockpot. Would it be okay in there at all the same times and with the same ingredients? I don’t have enough stuff on hand to double. Thanks!
