Simply put the chicken into a large bowl or plastic bag shake in some sauce & give the chicken a really good massage - getting the sauce into the chicken
Leave to marinade in the fridge or overnight would be good and if you've got time.
Light the BBQ, & wait until the coals are covered with ash .
At this stage there should be no flames
Put the chicken onto the grill (it cooks better raised up on a rack on the grill) & turn now & then until all the juices run clear - about 40 minutes to an hour depending on the size of your chicken.
Make sure it is cooked - NO PINK - we don't want any bad tummy's
Once the chicken is cooked leave to rest for 10-15 minutes.
Put onto a serving platter or carve into portions & let everyone help themselves.
