This is a great crockpot recipe. If you choose to use boneless, skinless chicken breast you should just coat the chicken and either grill them or bake them in the oven as putting them in the crockpot they tend to dry out.
1 to 2 lbs of bone-in chicken pieces
2 Tablespoons soy sauce
1/4 cup oil
4 teaspoons sesame seeds
1/4 cup brown sugar
1 teaspoon ground ginger
Combine all ingredients except for the chicken and mix well. Place chicken pieces in the crockpot and pour the sauce over the top. Cook on low for about 6 hours.
If you decide to bake your chicken in the oven, bake at 350 degrees for about an hour, turning the chicken once during baking and rebasting with the sauce.
