Season the pork fillet with salt and pepper and fry in hot clarified butter, leave to cool. Soak the toast with milk, mix with the egg, pork meat and herbs.
Surround the fillet with the meat batter and wrap it in the cabbage leaves. Place the puff pastry sheets on top of each other, roll them out into a rectangle and wrap the prepared meat in them. Decorate with leftover puff pastry and brush with egg yolk.
