Preheat oven to 350 degrees F (175 degrees C). Coat a 9×13 inch baking dish with cooking spray.
Sprinkle 1 teaspoon parsley and 1 teaspoon basil evenly over the bottom of the baking dish. Arrange chicken breast halves in the dish, and sprinkle evenly with garlic slices. In a small bowl, mix the remaining 2 teaspoons parsley, remaining 2 teaspoons basil, salt, and red pepper; sprinkle over the chicken. Top with tomato slices.
Bake covered in the preheated oven 25 minutes. Remove cover, and continue baking 15 minutes, or until chicken juices run clear.
