Pre-heat oven to 450 degrees F.

Separate the egg whites from the yolks placing the yolks in 4 separate bowls and the whites all in one big bowl.

Whisk the egg whites until they have become solid and form stiff peaks.

Add in the bacon, spring onion, and cheese. Stir thoroughly.

On a lined baking sheet, separate the egg mixture into 4 clouds making a well in the center of each egg cloud.

Bake egg white clouds for 4 minutes, remove from oven, and add the yolks gently into each well.

Bake for an additional 4 minutes or until the egg white just start to brown and the yolks have set.

Sprinkle with salt & pepper and serve immediately!
