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.
Prepare three bowls: put the beaten egg whites in one bowl. In a larger bowl, combine whole wheat pastry flour, panko breadcrumbs, seasoned bread crumbs, grated Romano, salt, and pepper.
Bring a pot of water to a boil and cook the frozen ravioli for half of the package's recommended time (about 2–3 minutes); they should be slightly tender but still firm. Use a slotted spoon to transfer them to a tray and let cool until safe to handle.
Lightly spray the cooked ravioli with nonstick spray to keep them from sticking together and to help the coating adhere.
Working one at a time, dip each ravioli into the egg whites, then press into the breadcrumb mixture until thoroughly coated. Place coated ravioli on the prepared wire rack. Repeat with remaining ravioli.
Give each coated ravioli a quick spray of nonstick spray to promote browning. Bake in the preheated oven for 15–18 minutes, or until golden and crispy.
Serve the crunchy ravioli hot with marinara sauce for dipping and additional Romano if desired.
