This made the chicken really sweet, almost too sweet in my opinion. But if you are a fan of really sweet chicken, go for it! Next time I am going to try regular orange juice instead of frozen to see if it makes a difference.
3-4 Chicken Breast
1 tsp balsamic vinegar
3 T Ketchup
6 oz frozen Orange Juice concentrate
4 T Brown Sugar
Cook on low 5-6 hours, high 2-3 hours. Serve with rice
