Crock Pot Lemon Chicken

4 boneless, skinless chicken breasts, cut in strips
1/2 cup flour
1 Tbsp salt
1/4 tsp pepper
6oz frozen lemonade concentrate (just use half of a 12oz can)
3 Tbsp brown sugar
1 tsp balsamic vinegar
3 Tbsp ketchup
1/4 tsp red pepper flakes

Mix flour, salt, and pepper in shallow container. Dip chicken in flour mixture and brown in a small amount of oil. (You don’t need to cook the chicken all the way, just brown it up.) Place chicken in crock pot. Combine remaining ingredients and pour over chicken. Cook on High for 4 hours or Low for 6-8. I cooked mine on high for 1 hour, then turned it to low for about 4 hours and it worked perfectly. Serve over rice.
