Preheat the oven to 230° Celsius

Place the bacon into a cold frying pan

Place onto a medium to high temperature and cook until to your liking

Remove from the heat, slice and set aside to cool

Once the oven is preheated separate your eggs

Place the egg whites into a mixing bowl

Place each egg yolk into a separate container - I used egg cups

Season the egg whites and whisk until firm

Fold in the bacon and cheese

Spoon 2 portions per person onto a lined baking sheet

Make them as round as possible, and depress the centre to make a well

Bake for 4 minutes

Remove from the oven and carefully place an egg yolk into the centre of each egg white nest

Bake for 2 minutes

Season the yolk with salt and serve immediately
