Preheat grill to approximately 275ºF. Mix together barbecue sauce and Cholula Chipotle. Reserve 1/2 cup of mixture to use as a finishing sauce at the table.
Place ribs in a foil pan. With a fork, lightly perforate the pan to allow the juices to drain. Place pan on grill and cook for 2 - 2 1/2 hours until tender. Turn up heat, generously baste both sides of ribs with sauce mixture and grill for additional 10 - 15 minutes over direct heat until grill marks appear.
Smother the chicken with sauce mixture and place in refrigerator for about 1 hour.
Grill chicken for about 7 - 8 minutes on each side until done.
Serve chicken and ribs with remaining sauce mixture.
