Preheat the oven to 450 F

Separate the yolks from the whites. Keep each yolk in it's own small bowl for later use.

Whip the whites with an electric mixer until stiff peaks form

Fold in the cheddar, chives and salt and pepper

On a parchment lined baking sheet, spoon large dollops of the whites onto the baking sheet, creating 4 clouds. Press the back of a spoon on the center to create a shallow well for the yolk.

Bake for 3 minutes or until it just starts to golden

Add one yolk to each cloud and place back in the oven for 3-4 more minutes

While the yolks are baking, toast up bread on both sides. Generously butter one side.

Remove the eggs from the oven and place a cloud on each piece of toast

Sprinkle with additional chives and enjoy!
