Preheat oven to 350 degrees. With a meat pounder, pound chicken breasts into large, flat pieces of 1/4-inch thickness.
Season insides of chicken breasts with 1/4 teaspoon pepper and salt. Combine rice, tomato, cheese, basil, and remaining 1/4 teaspoon pepper. Spoon rice mixture on top of pounded chicken breasts; fold over and secure sides with wooden toothpicks soaked in water. Wipe off outsides of chicken breasts with paper towel.
Coat a large skillet with cooking spray and place over medium-high heat until hot. Cook stuffed chicken breasts one minute on each side or just until golden-brown on the outside. Transfer chicken to a shallow baking pan. Bake at 350 degrees for 10-15 minutes, until chicken and stuffing registers 165 degrees on a meat thermometer. Makes 4 servings. Enjoy!
