Salt & pepper to taste
Preheat oven to 400. Spray muffin tin with pan. Using a glass or 3" ring cutter cut a circle out of your bread. Take one piece of bacon and form it around the inside top of muffin tin. Take piece of bread and smoosh it into the muffin tin so that the bacon is between the bread and the pan. Put a small amount of shredded cheese on top of the bread and crack on egg on top of the cheese. (Note, if you use Large eggs, you might want to keep some of the white out or it will overflow). Season with salt and pepper to taste. Bake for 15 minutes until whites are set. Use a knife to loosen the edges and remove. Allow to cool for a few minutes before eating.
*Note: I saw this floating around on pinterest and I had been dying to try it. The recipes I read didn't tell me that I might need more then one piece of bacon to fit around the tin. I used the precooked bacon and just put it straight in the pan. If you want to use real bacon you have to cook it without letting it get crispy because it will continue to cook in the oven, and if it is crispy it will break when you try and form it into the pan.
