First, find a stick around your campsite that forks out into 2 or 3 small prongs that will be thick enough to hold up your grilled cheese sandwich. You may. Have to snap the branches to get the stick to a manageable size.
Then put your stick over the fire to burn off any bacteria and rub off any loose debris.
Prep your grilled cheese by buttering the outsides of the bread and sticking a couple slices of American cheese in the center.
Rake some of the hot coals from the outside of your fire to the side to create a small bed of coals to cook over.
Place your grilled cheese on your makeshift stick that you will use to hold over the small bed of coals. The prongs that fork out from the end of the stick should provide enough support to hold your grilled cheese, but be careful not to move it too much or it may topple over into your coals and you will have to start over.
The cooking time for your grilled cheese will depend on how hot your coals are and how high you hover the bread over them. Typical cooking time is roughly 2-3 minutes per side. The first time you attempt this we recommend holding it higher up to avoid burning the bread. A good distance is about 4-5 inches above the coals.
