Heat oven to 375°F. Place four 6-oz custard cups upside down on cookie sheet with sides. Spray cups with cooking spray.
Unroll dough on work surface; press into 12x8-inch rectangle. Cut into 4 squares. Place 1 dough square over each custard cup, stretching to fit bowl.
Bake 12 to 15 minutes or until golden brown. Cool 5 minutes. Remove from custard cups. Place on cooling rack.
Meanwhile, in 2-quart saucepan, melt butter over medium heat. Add onion; cook about 2 minutes, stirring occasionally, until tender. Add flour, salt and pepper; stir until well blended. Gradually stir in broth; cook and stir until bubbly and thickened. Stir in chicken, black beans, green chiles and corn. Simmer about 5 minutes or until hot.
Spoon about 3/4 cup chicken mixture into each crescent bowl. Top with cheese and salsa.
