I cook bacon in the oven, so I always start with that step first. If you prefer to cook your bacon in a skillet, that's fine too, just improvise accordingly. Line a rimmed cookie sheet with foil and place bacon onto sheet placing it into a cold oven. Turn oven to 400 degrees. I usually cook the bacon for about 14 minutes because I like it crispy. If you don't like it as done, shorten the cooking time.While bacon is in the oven, take a cookie cutter (or use an empty can or small mug) to cut a circle or square from the center of the bread (personally, I like cutting a square). I save the cut out bread in a baggie for either homemade bread crumbs, or a small mid day snack smeared with some peanut butter.Melt the butter in a large nonstick frying pan over medium heat. While the butter is melting, crack the eggs into a small cup and break the yolk (you don't have to break the yolk, I just prefer it that way). Add the slices of bread to the frying pan and pour eggs into the hole (nest); season with salt and pepper. Cook for about 3 minutes or until the bottom is a nice golden brown. Gently flip using a flat spatula and continue to cook for an additional 3 minutes.Meanwhile, the bacon should be done (or close to it). Once the bacon is done, remove it from the oven and place on a paper towel lined plate; carefully throw away foil being careful not to burn yourself on the bacon fat. Chop bacon with a knife or crumble with your fingers.Remove Birds in a Nest from frying pan and place on rimmed cookie sheet. Evenly sprinkle the cheese and bacon on each slice and place in the warm oven. Please note: Do not turn the oven back on. You just want a little bit of gentle heat to melt the cheese. Once the cheese is melted, remove from oven and serve immediately.
