A mountain pie is a sweet or savory pie made in a cast-iron cooker. Most mountain pies are made with ingredients sandwiched between two slices of bread or other dough. Mountain pies are also called pie irons, hobo pies, tonka toasters, jaffles, or pudgy pies. Typically mountain pies are made over a campfire, but the pie irons can also be cooked on a camp stove or grill.
