Preheat oven to 450 degrees. Place wax paper on a Baking Sheet and coat with Cooking Spray.
Separate the Egg Whites and Yolks, placing the egg whites in a mixing bowl and the yolks in a smaller bowl as to not disturb the yolks. Using a whisk or hand mixer, beat the egg whites for 3 minutes or so, until stiff peaks form.
Carefully, fold in Parmesan Cheese and season with Salt and Pepper. Spoon 5 mounds of the Egg Whites onto the prepared Baking Sheet and make an indent in the center of each mound to form a nest. Bake until Lightly golden for 3 minutes.
Remove from the oven and spoon an egg yolk into the center of each nest and season with salt and pepper. Baked until yolks are just set, for about 3 minutes.
Garnish with the crumbled Bacon and chopped Green Onions.
