1. Preheat oven to 400°F.

2. Cook ground beef, onion and next 3 ingredients in a large nonstick skillet 5 minutes or until beef is browned; drain. Add corn and next 2 ingredients and cook until heated through. Remove and let cool.

3. Working with one wonton wrapper at a time, spoon 1 tablespoon beef mixture into center of each wrapper. Bring 2 opposite corners together and pinch the points to seal, forming a triangle. Place wrappers on a wire rack and repeat procedure with remaining wrappers and beef mixture.

4. Place empanadas on lightly greased baking sheets and coat lightly with cooking spray. Bake 4 to 6 minutes on each side, turning once or until golden. Serve with salsa and sour cream, if desired.
