I make this when I don't have a lot of time or when I just can't think of anything else. The kids like it just as much as we do, which doesn't happen very often. It's super easy.
4 frozen chicken breasts
1 can cream of chicken soup
16 oz. sour cream
1 pkg. Lipton onion soup mix
Place frozen chicken breasts in crockpot. Mix the remaining ingredients and pour over the chicken. Cook for 4-6 hours on low.
Serve chicken and sauce over rice. We like it with a side of steamed broccoli. Yum!
Also, if you haven't tried crockpot liners, please do! You'll use your crockpot a lot more--I promise.
