Let stand 15 minutes. Peel and coarsely chop, reserving any liquid.

Combine breadcrumbs, panko, cheese, 1/2 teaspoon salt, and black pepper in a shallow dish. Dip zucchini in egg substitute; dredge in breadcrumb mixture. Place zucchini on a wire rack coated with cooking spray. Lightly coat zucchini with cooking spray. Bake at 400° for 25 minutes or until golden brown. Serve immediately with sauce.
