Spray a 5-7 quart slow cooker with nonstick cooking spray.

Add soup to the crockpot insert, then fill the soup can with chicken stock or water and add it to the crockpot. Add the spices, then stir to combine. Place the chicken in the soup mixture and top with mushrooms.

Cover and cook on high for 2-3 hours or low 4-6 hours, or just until chicken is cooked through.

Remove chicken from the crockpot and let sit for a few minutes. While waiting, stir together cornstarch and water and stir into the crockpot mixture. Cover.

Shred the chicken and return it to the sauce in the crockpot. Set to warm until ready to serve.

Serve hot with rice or vegetables.
