Heat oven to 375 F.

Using a 12 inch cast iron skillet, fry the bacon, drain, set aside.Remove any excess bacon grease, leaving just enough to coat the pan. Add cubed potatoes, and spread out in pan. Salt and pepper them, and allow to brown. After about 5 minutes or so, turn potatoes over, and season again. Cover the pan with a lid, to allow potatoes to steam to cook through. This may take another 5010 minutes. Test potatoes for doneness when fork goes through easily.

While potatoes are frying, whisk eggs, sour cream, & pepper in a large glass bowl with a pour spout. Set aside.

When potatoes are done, add in the egg mixture.
