If you want to cook them in sausage fat instead, drain all but about a tablespoon and heat the pan on medium high.Break 6 eggs into a bowl, add them to the pan and poke the yolks.Stir a bit just to spread the yolks around a bit.Cook until just set and remove from pan.Spray either your cast iron skillet or 8x8 inch pan with cooking spray.Cut the English muffins into chunks and toast at 375 degrees until slightly browned and crispy, about 7-9 minutes.Whisk the rest of the eggs, milk, salt and pepper in a mixing bowl.Add toasted English Muffin chunks, eggs, sausage and cheese in layers to your pan.Pour the egg mixture over it evenly.Bake for 45-50 minutes.Enjoy with Maple syrup!
