1. Preheat oven to 425°.
2. Combine first 4 ingredients in a bowl; stir until well blended.
3. Working with 4 wonton wrappers at a time (cover remaining wrappers with a damp towel to keep from drying), brush edges of wrappers with milk. Place about 1 rounded teaspoonful of cheese mixture in center of each wrapper. Bring 2 opposite corners together; pinch edges to seal, forming a triangle. Brush both sides of ravioli with milk; dredge in breadcrumbs, pressing gently with fingertips to coat. Place on a large baking sheet coated with cooking spray. Coat ravioli with cooking spray.
4. Repeat procedure with remaining wonton wrappers, milk, cheese mixture, and breadcrumbs.
5. Bake at 425° for 7 minutes or until lightly browned. Serve warm with sauce.
