In small bowl, beat together milk and egg. Dip each ravioli into egg mixture; coat with crumbs.
In a heavy 3-quart saucepan, heat 2 inches of cooking oil to 350 degree F. Fry ravioli, a few at a time, in hot oil about 1 minute per side or until golden. Drain on paper towels; keep warm in 300 degree F oven while frying the rest.
Heat sauce. Sprinkle ravioli with Parmesan. Serve with warm sauce for dipping. Makes 12 to 14 appetizers.
