Combine the coating ingredients in a small dish and stir to mix well. Set aside.
Scrub the potatoes, dry well and cut into 1/2-inch thick strips. Place the potatoes in a large bowl. Pour the egg white or egg substitute over the potatoes and toss to coat evenly. Sprinkle the coating over the potatoes and toss again to coat.
Coat a large baking sheet with nonstick cooking spray and arrange the potatoes in a single layer on the sheet, making sure that the potato strips are not touching one another. Spray the tops lightly with cooking spray, and bake at 400 for 25 to 30 minutes or until nicely browned and tender. Serve hot.
