1/8 cup Dijon mustard
1/8 cup chopped fresh parsley, divided
1-1/2 tsp. dried thyme
2 bone-in chicken breasts, skinned
1/8 tsp. salt
1/8 tsp. freshly ground black pepper
1/2 tbsp. olive oil
3/4 cup chopped onion
2 garlic cloves, minced
1/2 cup dry white wine
1/2 cup fat-free, less-sodium chicken broth
Combine mustard, 1/2 tablespoon parsley, 3/4 teaspoon thyme, and chicken in a large zip-top plastic bag; toss well to coat. Chill 8 hours or overnight. Remove chicken from bag, and discard marinade. Sprinkle chicken with salt and black pepper. Heat olive oil in a large Dutch oven over medium-high heat. Add chicken to pan, and cook 5 minutes on each side or until browned. Remove from pan. Add chopped onion to pan, and sauté 5 minutes or until tender, stirring frequently. Add garlic to pan, and sauté 1 minute, stirring constantly. Stir in wine and chicken broth, scraping pan to loosen browned bits. Stir in 1/2 tablespoon parsley and remaining thyme. Return chicken to pan. Cover, reduce heat, and simmer 25 minutes or until chicken is done. Remove chicken from pan with a slotted spoon. Keep warm. Cook sauce, uncovered, over medium heat 4 minutes or until slightly thick. Pour sauce over chicken, and sprinkle with remaining parsley.
