Chipotle BBQ Chicken with Potatoes and Onions

HEAT grill to medium to medium-low heat.

RINSE chickens; pat dry. Cut out back bone from each chicken with kitchen shears or sharp knife. Open chickens butterfly-style.

MIX barbecue sauce, peppers and garlic until well blended. Combine potatoes and onions in medium bowl. Add 1/2 cup barbecue sauce mixture; toss to coat. Spoon onto center of each of 4 (12-inch) square sheets heavy-duty foil. Bring up foils sides. Double fold top and ends to seal each packet, leaving room for heat circulation inside.

GRILL chickens 15 min.; turn. Add packets; grill 25 to 30 min. or until chickens are done (165ºF) and vegetables are crisp-tender, turning occasionally and brushing chicken with remaining barbecue mixture for the last 15 min. Cut slits in foil to release steam before opening packets. Cut up and serve one of the chickens with the cooked vegetables. Cool remaining chicken, then cover and refrigerate to use to prepare BBQ Chicken Arepa Melts another night.
