Cook bacon in a pan on medium-high heat until it is nice and crisp.
While bacon is cooking, do the following:
-Lightly toast the bread, just long enough to firm it up without taking on color.
-Crack one egg into a cup then add the water, salt and pepper. Whisk thoroughly with a fork to combine.
When bacon has finished cooking pour the egg mixture in a heated 9” non-stick pan (medium heat) coated with some of the bacon grease.
Swirl the pan as needed to spread the eggs evenly across the bottom and sprinkle with salt and pepper.
When the egg appears to have almost cooked through and slides easily in the pan, flip it over. Let cook for a few seconds, and then fold the egg as needed to fit the bread.
Top with cheese and bacon then place on sourdough.
Toast both sides of sandwich in heated pan with bacon grease until the bread takes on color but isn't burnt.
