from my friend, Heidi T.
4 chicken breasts - do not need to thaw, can be frozen
1 can cream of mushroom OR cream of chicken soup
1 package Lipton Onion Soup mix
2 cans mushrooms, drained
Put all ingredients in crock pot. Set on low for 8 hours or high for 4 hours.
Approximately one hour before serving, I like to take the chicken out of the crock pot, cut it up, and then return to crock pot for the last hour.
Stir in one cup of sour cream before serving.
Serve over rice, pasta, or mashed potatoes.
