The hobo pack, a self-contained, foil-wrapped meal cooked in hot coals, is an easy option for outdoor cooking. Though this recipe includes a lot of fall flavors, it is great for summer cookouts, a change from the usual suspects. The key to success is to be sure the foil packet is tightly sealed so no juices leak out. Be aware that the intense heat of the coals will deeply char some of the food that’s right up against the foil, but to us that’s the best-tasting part.
