As my sister was cleaning out her kitchen for her recent move, i inherited a few things from her pantry that she wasn't packing. One was a package of Reynold's Hot Bags. I hadn't used them before, but was glad to try them out recently. They hold a large amount and are basically a bag of heavy duty foil that rolls closed on one end to keep the heat and contents inside. It allows you to cook all your meat and veggies together in one container.
I filled it up with chicken breasts, corn on the cob, diced russet potatoes and frozen green beans. I added a couple teaspoons of butter and a variety of seasonings. It went on medium heat on the grill for about 1 1/2 hours and this is what we ended up with. You may be able to accomplish similar results with a roll of foil, but this heavy duty bag helps eliminate accidents.
