Preheat barbecue grill to 350 F. In a bowl, combine first 5 ingredients; add bacon slices & chicken thighs. Allow to marinate for about 15 minutes; drain. Reserve marinade.
On a large sheet of foil, place the bacon to form 4 crosses, top each with a pineapple slice in the center. Next, lay a chicken thigh on pineapple slice, fold bacon ends over thighs. Carefully flip over so that the bacon ends are on the bottom.
Lay foil on barbecue (with the wrapped chicken thighs on it). Close lid on cook until internal temperature reaches 165 F. and the juices run clear. If you prefer, use some of the excess marinade to baste meat as it cooks.
