Many people love to cook out while camping and that's great. But I like taking prepared meals that are easy and quick and can be cooked in a variety of methods. For instance, potato/shredded beef burritos are good wrapped in foil. They keep well, can be made at home and warmed on the campstove, on the fire, eaten cold, just about any way you want. Toss in a bottle of picante and instant belly full.
then you're back out hiking, tossing frizbies, shooting targets etc.
