Place frozen ribs into a 5-7 quart Crock Pot with onion. Turn on High and cook for 6 hours. Mix the Barbecue Sauce and Honey together in a bowl for basting. Set aside.
When ribs are done place them immediately on the grill (325 degrees - Medium heat). Baste the ribs with the sauce honey mixture for 10 -15 minutes. They will fall off the bones.
