Separate eggs, putting whites in a large bowl and yolks in four separate small bowls. Whip egg whites until soft peaks form. Fold in cheese, chives and turkey bacon
Spoon into four mounds on parchment-lined baking sheet; making a deep well in the center of each.
Bake at 450F for three minutes. Remove from oven and add one yolk to each well. Season with pepper.
Return to oven and bake until yolks are set, about three to four minutes.
