Place chicken between 2 sheets of heavy-duty plastic wrap, and flatten to 1/4-inch thickness, using a meat mallet or rolling pin. Sprinkle with salt and pepper.
Coat a large nonstick skillet with cooking spray; place over medium-high heat until hot. Add chicken; cook 3 to 4 minutes or until lightly browned. Turn chicken, reduce heat to medium-low, and cook 2 to 3 additional minutes or until done.
Add orange sections and remaining ingredients to skillet. Cook 2 to 3 minutes or until orange mixture is thoroughly heated. To serve, spoon orange mixture over chicken.
