The original recipe is from Fix-it and Forget-It Cookbook and was written by Mary Seislstad. I have made slight adjustments for freezing.
6 boneless, skinless chicken breast halves (original recipe calls for frozen chicken)
2 10 3/4oz. cans cream of chicken soup
4 oz. can sliced mushrooms, or 1/2c. sliced fresh mushrooms
3/4 tsp. salt
1/4 tsp. pepper
Place chicken in gallon Ziploc bag. Mix remaining ingredients in separate bowl and pour over chicken. Freeze standing up, so it will fit in the crock pot when you are ready to cook.
Cook from frozen. Remove plastic bag from frozen meal. Place meal in crock pot. Cook on low 10-12 hours. Serve over rice.
Freezer Friendz: I included cooked rice for you. Just add a little water and microwave to reheat.
