Heat oven to 350°F. Spray 12 regular-size muffin cups with cooking spray.
In 10-inch nonstick skillet, cook beef over medium heat 7 to 9 minutes, stirring occasionally, until beef is brown; drain. Stir in chili powder, cumin, green chiles and green onion whites. Stir in enchilada sauce. Cook 5 to 6 minutes longer or until sauce thickens. Remove from heat; cool 5 minutes. Stir in cheese.
