Place chicken breasts between 2 sheets of heavy-duty plastic wrap; pound to 1/2-inch thickness using a meat mallet or small heavy skillet. Sprinkle chicken with 1/4 teaspoon salt and 1/4 teaspoon pepper.
Place flour in a zip-top plastic bag. Working with 1 piece at a time, add chicken to bag; seal and shake to coat. Remove chicken from bag, shaking off excess flour. Repeat with remaining chicken.

Heat a large nonstick ovenproof skillet over medium-high heat. Coat pan with cooking spray. Add chicken; cook 1 minute. Turn chicken over. Place pan in oven; bake at 450° for 13 minutes or until chicken is done.
