For Filling: SPRAY broiler pan with no-stick cooking spray. Heat broiler to High. Coat chiles with oil for even blistering. Broiler-roast corn and poblanos, turning occasionally with tongs, until corn is lightly brown and poblanos are blackened. Cool. Cut kernels off cob with sharp knife. Peel off outer skin of poblano, remove seeds and chop. Combine corn, poblanos, black beans and cheese in mixing bowl.
SPOON 1 Tbsp. filling onto each round. Fold dough in half. Crimp edges with fork to seal. Repeat with remaining dough and filling. Prick top of empanada with tines of fork to vent.
