Simply empty the jar of sauce into a cast iron skillet or baking dish and set your chicken into the sauce. Use a spoon to spread some of it over the chicken.
Bake for about 40 minutes or until the chicken reaches at least 165 F. on a meat thermometer.
Pour this over some zucchini noodles and dinner is good to go!
Parmesan optional.
