We camp with groups that include kids every year. At least one meal is foil pouch dinners. No recipe--I just bring a variety of ingredients from the pantry to assemble-your-own, and everyone eats what they like!
Bring a generous array of veggies (raw: onions, broccoli, diced carrots, cabbage, diced sweet or white potatoes; canned corn, potatoes, carrots, mixed veggies, etc.; or if RVing use bags of mixed frozen veggies and thaw before assembling), meats/proteins (diced raw or cooked chicken, canned black beans, cheese cubes, ground beef, shredded pork, precooked bacon, sliced kielbasa, chunks of bratwurst or other sausages), and sauces/seasonings (bbq sauce, garlic salt, salsa, ranch dressing, soy sauce, hot sauce packets, you name it!).
I hand a smaller bowl to kids and tell hem to fill it up with what they like from the "ingredient buffet", and use a larger bowl for adults. Then they bring their filled bowl to my wrapping station. Dump the bowl in the center of a large square of heavy-duty foil, add any sauces or seasonings that the eater desires, then wrap carefully, folding edges of the foil together tightly several times to seal the pouch completely. Cook elevated over coals for an appropriate time (depending on whether using raw or precooked meats and veggies). Cut open onto a plate to cool and eat.
