Sweet and Sour Chicken

Ok I found this on Pinterest (go figure right?) and tried it out last night! It turned out pretty good. My little sister LOVED the chicken. I thought it was missing something. Just not sure what yet.

4 chicken breasts
1 can pineapples in JUICE
1/2 cup brown sugar
1/2 cup soy sauce

Put everything in the crock pot on low for 8 hours or high for 4. My chicken breasts were frozen, so you may need to tweak the cook time a little. Serve over rice. ENJOY :)
