Onion Chicken in Balsamic Sauce

This is what Aaron made for Mother's day dinner, he can't leave a recipe alone either, so I included the changes. We served it over noodles for the boys and dipped bread in the sauce.

Onion Chicken in Balsamic Sauce

INGREDIENTS
1 tablespoon olive oil
1 onion, chopped
2 chicken breasts cut into large chunks
4 cloves garlic, chopped
1 cup chicken stock
1/4 cup balsamic vinegar
1/4 cup chopped sun-dried tomatoes
1 Tbsp. cornstarch
salt and pepper to taste

DIRECTIONS
Preheat oven to 350 degrees F (175 degrees C).
In a large skillet, heat oil over medium heat. Add onion and reduce heat to low. Allow onion to caramelize, stirring only enough to prevent sticking and to be sure that all sides are fully cooked. Add garlic and saute briefly.
Increase heat to medium. Add chicken hindquarters to skillet and brown on both sides. Remove chicken, onion and garlic and place in a slow cooker.
Combine the stock and vinegar and corn starch. Pour mixture over chicken and stir in the sun dried tomatoes. Cook on high in slow cooker for 20-40 minutes, or until chicken is done and juices run clear.
