Directions

• Preheat oven to 400°. In a shallow dish, whisk 2 tablespoons oil, 1 tablespoon balsamic glaze and 1/4 teaspoon salt. Add chicken; turn to coat. Let stand 10 minutes.
• In a large cast-iron or ovenproof skillet, heat 1 tablespoon oil over medium heat; brown chicken on both sides. Bake 12 minutes. Top with cheese. Bake until a thermometer reads 165°, 3-5 minutes longer.
• Meanwhile, for topping, in a large skillet, heat oil over medium heat. Add shallots; cook and stir until tender, 2-3 minutes. Add garlic; cook 1 minute longer. Stir in tomatoes, salt and pepper. Cook and stir until tomatoes are tender, 2-3 minutes. Remove from the heat. Stir in basil.
• To serve, spoon topping over chicken. Drizzle with balsamic glaze. If desired, sprinkle with red pepper flakes and additional basil.
