Spray a generous amount of non-stick cooking spray on inside of both sides of the pie iron.
Choose your filling of choice (lemon or caramel) and spread on both pieces of bread and place on the pie iron.
Add the 2nd filling to the pie iron. For lemon meringue, I used 4 small marshmallows, and for the caramel, I cut 2 Lindt chocolate balls in half.
Close the pie iron, cut off the bread edges. I cut off the bread edges during the toasting, as I find it's easier to cut off crispy bread, your choice.
Cook over your campfire, turning often to get it nice and golden brown inside. The iron needs to heat up and this will take at least 5 minutes, but depends on how hot your fire is and how close you are holding it (hold it pretty close).
When the pie is golden brown, carefully remove from pie iron and allow to cool, as the insides are incredibly hot. Seriously, allow to cool so you don't burn your mouth.
Enjoy and repeat! The combinations are endless!
