Preheat the oven to 450 degrees F. Coat a baking sheet with cooking spray.
Slice the zucchini into 1/4″ thick rounds. In a medium bowl, toss the zucchini with the beaten egg. In a small bowl, combine the Parmesan, bread crumbs and freshly ground Southern spice blend. Dip each round into the Parmesan mixture, coating both sides and place in a single layer on the prepared baking sheet.
Bake the zucchini rounds until browned and crisp, 15 to 20 minutes. Enjoy immediately!
