Step 1) Whisk together oil, wine, lemon juice, and seasonings in a small bowl. Place chicken breasts in a resealable plastic bag and pour marinade over. Turn bag to cover completely and refrigerate for at least 30 minutes.
Step 2) Remove chicken from marinade; discard marinade. Place chicken on grill and brush with orange juice concentrate. Grill for 10 to 12 minutes or until cooked through, turning once halfway through.
