Place 5 slices of bacon in a cold cast iron pan. Place over medium heat and cook the bacon until it is done Set the bacon aside on a plate, but keep the grease in the pan.
Add bite sized pieces of potatoes to the pan, and cook for about 10 minutes, turning the potatoes on all sides so they brown evenly.
Move the potato so it creates a gap large enough to crack the egg in. Carefully crack the egg as to not break the yolk. Cook for another 5 minutes.
Crumble bacon and toss in the pan. Sprinkle cheese over the pan, then a dash of salt and paprika. Mangia!
