Whisk together two eggs. Add 2 boxes of Jiffy cornbread mix, 1 cup milk, and melted butter and whisk together to combine. Add green chilis and stir.
Spray the inside and lip edges of the pie iron with cooking spray. Add 1/4 cup cornbread mix to the bottom.
Place pulled pork and pepper jack cheese on top. Then add another 1/4 cup of cornbread mix and close pie iron. Do not flip over the pie iron yet!
Keep the pie iron face up and place on a flat grill grate over the campfire. (If you tilt the pie iron in the beginning of cooking, the cornbread mix will ooze out.)
Cook for approximately 15 minutes, flipping halfway through.
