Drain the potatoes then rinse the egg in cold water before peeling and cutting into quarters. Mash the potatoes with butter, season, then set to one side.

Add the pieces of egg, herbs and mustard to the sauce and season with ground black pepper, then pour into an ovenproof dish. Top with the mashed potato, using a fork to rough up the top. Grill for 4-5 minutes until golden and bubbling then serve immediately on warmed plates.
