Thanks for sharing the recipe. I just harvested the first sprouts from my garden and was wondering how to cook them.

I've got a different type of grilling pan that would work well for roasting brussels sprouts, and you wouldn't have to bother with the skewers. It's a rectangular pan with small round holes cut through it. It's designed to sit on top of the rack on the grill, so you can cook smaller foods like this without them falling through. You can place the food on it and easily stir it around to grill it evenly. I like it for things like mushrooms or making rosemary roasted potatoes. It's small enough so that you can use the other half of the grill for the meat. Because of the holes, the food gets some of the "grilled" flavor it wouldn't get from a solid pan.
