01 - Preheat the pie iron over a campfire or stovetop for 2 to 3 minutes.
02 - Brush one side of each bread slice with melted butter. Arrange 4 slices, buttered side down, on a clean work surface.
03 - Spoon 2 tablespoons pizza sauce onto each bread slice. Sprinkle evenly with shredded mozzarella, then add preferred toppings and dried Italian herbs if desired.
04 - Place remaining bread slices on top, buttered side facing up, to form sandwiches.
05 - Place each sandwich into the preheated pie iron. Close and secure the iron, trimming off any excess bread around the edges.
06 - Cook over medium campfire heat for 3 to 4 minutes per side, until the exterior is golden brown and cheese is melted inside.
07 - Carefully open the pie iron. Transfer pockets to a plate, allow to cool briefly, and serve immediately.
