Preheat a non stick sauté pan over medium heat.
Prepare some bread crouton by sauteing the bread pieces in a warm sauté pan or in the oven for 5 minutes. Remove from the heat and keep warm on a kitchen paper to remove excess oil.
Sprinkle the parmesan and cheddar. Let the cheeses melt and start to colour and create a crusty skin for a minute or so depending on the heat.
Add the fried egg and add some butter to the pan.
Spoon the butter over the eggs and cover with a lid.
Cook for a further 2 minutes or until the egg white is opaque yet the egg yolk still soft and runny or to your liking.
Season well and turn off the heat while cooking the fried eggs.
Remove from the heat, carefully lift the crispy cheese layered fried egg and serve immediately with the croutons and some salad leaves.
