Separate the yolk from the white of the remaining egg and lightly beat the egg white. Add the parsley, mixed herbs and sausage meat and mix together. Season with salt and freshly ground pepper, then divide into four equal portions. Use your hands to pat each portion into a flat disc. Place a hard-boiled egg on each disc and wrap the meat around the egg, ensuring a good seal. Roll them in fresh breadcrumbs then chill them for at least 10 minutes.
Bake on a baking sheet in a preheated moderately hot oven (Mk 5 - 375ºF - 190ºC) for 25-30 minutes until golden brown. Cool, then serve with a side salad.
