To a large bowl add the eggs, milk, salt, and pepper whisk well.
Generously grease a sheet pan with non-stick spray. Add butter to the sheet pan and spread the butter out with the back of a spoon or a brush. Sprinkle the bacon, cheese, bell pepper, and spinach all over the sheet pan pour the egg over the top and spread it out as even as possible.
Bake for 20 minutes or until the egg has set. Enjoy!
