I made this breakfast on our last morning camping, and was really quite proud. First I layered bacon like a pie pan in a cast iron skillet, then topped that with very thin slices of potato. On top of a 2-slice thick layer of potatoes, I piled in the green chile + mashed potatoes + bleu cheese we'd had the night before, and created wells in them. In the wells, I broke two eggs, then nestled the whole shebang into an open fire of coals, topped with another cast iron.
In about 15 minutes, all was warm and done like a potato layered pie. I wish I could cook everything in cast iron.
