Spray your pie iron with cooking spray. (Alternatively, your bread can be buttered. I just find the spray to be a bit easier.)
Place one piece of bread on one side of the pie iron. Top with your desired fillings.
Add the second bread slice to the other side of your pie iron and close.
Cook over a hot campfire until golden brown and hot inside: about 5-7 minutes. Flip the iron while it is in the fire so the mountain pie cooks evenly. Be sure to check on your mountain pie throughout the cooking process to avoid burning.
.Remove the cooked mountain pie from the iron and let it cool for a few minutes before enjoying.
Notes
