Preheat oven to 450 degrees. Line baking sheet with parchment paper (or foil will work, but parchment paper works best), and spray with non-stick cooking spray.
Wash zucchini and slice into 1/4 inch slices.
Mix the bread crumbs, Parmesan and seasoning in one bowl. Place the egg whites in another bowl.
Dip zucchini slices in the egg whites, followed by the breadcrumb mixture, coating them evenly.
Spread zucchini out on in a single layer on the baking sheet. Roast 7 minutes. Turn zucchini over. Roast another 7-8 minutes, or until coating is crispy and golden brown. Serve immediately.
