Boil the eggs fifteen minutes. Line a dish with very thin slices of bread and fill with layer of eggs cut in slices, strewing them with a little grated bread, pepper and salt; rub the butter with the flour, put it in a saucepan with the parsley, onion, salt, pepper and the milk or cream; when hot pour over the eggs; cover the top with grated bread crumbs and put it in the oven, let it heat thoroughly and brown.
