Paper lunch bag
Marshmallow roasting stick
Campfire with hot coals and little flame.

Per person:
2 strips bacon
handful of frozen hash browns
1 or 2 eggs
salt and pepper

Lay bacon in bottom of bag.
Add potatos.
Add eggs.
Close bag by folding top 1/3 down, then fold that in half and in 1/2 again.
Poke through the folded portion with the stick to hold it above the fire.
Hold 5 inches above coals for 10 minutes - might be better to prop up by sticking the other end of the stick in the dirt rather than hoping every boy keeps his bag out of the coals.
Open a bag to check. If its done, tear the top off the bag or fold it down and eat right out of the bag. But, since the bag is greasy, you'll want to sit it on a plate or something other than the table or pants leg.
