Preheat oven to 375 degrees. Spray 4 heavy duty squares of foil with nonstick cooking spray. Divide chicken between the foil squares. Sprinkle with salt and pepper. Set aside.
In a large bowl, combine remaining ingredients. Divide into 4 and spoon over chicken. Top with remaining cheese if desired. Close packets to seal and bake 30 minutes until chicken is cooked thoroughly.
Serve hot over rice, quinoa or anything else you like.
