We marinate chicken breasts and steaks and freeze them at home. Thaw them at camp and they're ready to grill. We grill foil wrapped baked potatoes and corn on the cob. Veggie Kabobs are great, too. We make hobo (foil packet) dinners almost every time we camp. Pie Irons are a favorite, you can make almost anything in them. Make a salad or two at home and bring them along, pasta salad, coleslaw, bean salad, things that keep well.
We've also added these to our dry camping rotation. We make them regularly, they're easy, fun and tasty:
