3 boneless, skinless chicken breasts
¼ cup balsamic vinegar
1½ tablespoons olive oil
1 teaspoon herbes de Provence
1 teaspoon Kosher salt
1 teaspoon freshly ground black pepper
In a small bowl, whisk together the balsamic vinegar, olive oil, ¾ teaspoon salt and ½ teaspoon pepper. Place chicken in a resealable bag and pour marinade on top. Refrigerate for at least two hours, turning the bag occasionally.
Heat a grill pan to medium-high heat and add chicken. Sprinkle with herbes de Provence, ¼ teaspoon salt and ½ teaspoon pepper. Grill until chicken is cooked through, about 6 minutes per side.
