I've been without an oven for a year and a half and I'm getting pretty good at roasting meats in the propane grill. Try something different for your next cookout or camping trip by roasting a pair of chickens this simple way. It takes less attention than grilling and you don't get any grease flares. This will work best on a grill that has 3 burners running front to back so that you can turn on the side burners and leave the center unlit. Note: Prep time does not include marinating time.
