Here is a few fun ones:
Bacon and eggs in a paper bag.
Take a brown paper lunch sack. (still sell them at Walmart)
open and line the bottom with 3 pieces of bacon. Crack 2 or 3 eggs into the bag.
Now fold over the top a few times and poke onto a stick and suspend over fire.
It will be done in about 7-10 minutes and presto... Breakfast bag individual serving!!
Peanut butter and jelly sticks:
Get the tubes of croissant rolls or dinner rolls/bread sticks that come in those ready to bake tubes.
Cut a green branch an inch or so thick and remove bark. Now unroll the bread dough and wrap around stick in a tubular fashion and lay over fire to cook. Slide off and smear peanut butter and jelly inside and hand to the closest kid.
Banana Boats:
Cut a banana with a lengthways flap leave on peel and cut out a sliver of banana. (eat that) Next fill cavity with marshmallows and Hershey's chocolate and close peel back. Wrap in foil and lay in the coals for about 5 minutes.
My son did this one at a Boy Scout cooking exhibition and took second place in his district. These are phenomenal.
My favorite side item:
Sliced potatoes in foil with onions.
Slice up about 5 potatoes and add onions, butter, salt and pepper, plus some garlic powder and season salt... (all to taste)
Wrap in a flat double layer of tin foil and lay on the grate over fire. Flip once after about 5-7 minutes and normally is done within 15 minutes. Maybe 20 if your fire is low.
Other have said this but:
Pouch meals
Dutch oven cobblers
Just google some good recipes.
Have fun!!
