How long should you cook boneless barbecue pork chops?

First, it would depend on how thick the chops are - the thicker they are, the longer they will take to cook. I find that the less they are turned (i.e. only once), the more tender they are. The actual test for doneness is to cut into the center of the thickest chop. It MUST be white with NO pink. Pork has to be well cooked to destroy the potentially very dangerous trichinosis worm or its eggs.
