Preheat the oven to 450°F (230°C). Line a baking sheet with aluminum foil and set a wire rack on top; spray the rack lightly with nonstick spray.
Whisk the egg whites in one bowl until smooth. In a larger bowl combine the whole wheat pastry flour, panko, seasoned bread crumbs, grated Romano cheese, salt, and pepper.
Bring a pot of water to a boil and cook the frozen ravioli for half the package's recommended time (about 2–3 minutes for most ravioli). Drain well.
When the ravioli are cool enough to handle, lightly spray them with nonstick spray to prevent sticking. Dip each ravioli first into the beaten egg whites, then press into the breadcrumb mixture to coat thoroughly.
Place the coated ravioli in a single layer on the prepared wire rack. Lightly spray the tops with nonstick spray.
Bake in the preheated oven for 15–18 minutes, or until the ravioli are crispy and golden brown.
Serve hot with marinara sauce for dipping and extra grated Romano if desired.
