These have a really good sweet onion BBQ sauce on them. At first I thought that 1/4 c. would be way too much onion, but it cooks in really well, and the sauce isn't overpowered by them at all.
The original recipe called for this amount of sauce on 5 chops, but I usually only put in 3 chops (I'm not a fan of left-over meat and I'm only cooking for 2). If you were to make 5 chops, I would suggest doubling the sauce.
Also, depending on the type of chop, you may not need to cook as long (I've used small boneless loin chops and they only took about 1 hr 15 min)
