Cook bacon in cast iron skillet until done. Transfer to paper-towel lined plate to drain.
Add the corn tortilla pieces directly to the hot bacon grease, heat set to medium low. Toss and stir until browned and crispy (should resemble chips). Reserve ½, set aside.
Add eggs and cheese to skillet, scramble to break the yolks.
Add the diced Hatch green chilies, salt and pepper.
When eggs are cooked through, add the bacon and stir.
Plate your pile-o-migas, top with reserved fried corn tortillas, a pinch of cheese and chopped cilantro. Add a dollop of salsa on the side and enjoy!
