Preheat oven to 425°F. Cut zucchini into 3-inch sticks. Whisk an egg white in a small bowl and add milk. Combine Parmesan and seasoned breadcrumbs in a separate bowl. Dip zucchini sticks into egg mixture, and then roll in breadcrumb mixture. Coat a baking sheet with cooking spray, and place zucchini on sheet. Bake for 25-30 minutes or until golden brown.
