Lemonade Chicken

4 boneless, skinless chicken breasts

6 oz frozen lemonade, thawed (1/2 can concentrate)

3 tablespoons brown sugar

1 tablespoon vinegar

1/4 cup ketchup

Place chicken in greased slow cooker (I usually use only 2 chicken breast, but still the same amount of everything else.)  Stir lemonade concentrate, brown sugar, vinegar, and ketchup together.  Mix well.  Pour over chicken.  Cover and cook on high heat 3-4 hours or on low heat 6-8 hours.  A half hour before done, use two forks and shred the chicken.  Add more water to make more juice or to make the juice not so sour.  Cook for 15- 30 minutes more and serve over rice.
