Mushroom Chicken

3-4 boneless, skinless chicken breasts

Mix all ingredients (except chicken) until smooth.Pour over chicken. Cook in crock pot for 4-6 hours until chicken is done.(I usually put mine in around 10am and cook it on low and it's ready by dinner around 6pm)Serve over rice or mashed potatoes.
