a small bunch, leaves picked and finely chopped, stalks roughly chopped
zested and 1/2 juiced
garlic 2 cloves,
dried breadcrumbs 30g
Heat the wine in a large pan with the parsley stalks and onion. Bring to a simmer and cook for 5 minutes. Add the mussels, put the lid on and cook for 4 minutes, shaking the pan every minute, until the mussels have just opened.
Drain through a colander into a bowl and leave to cool for a few minutes until you can handle them.
Mix the lemon zest, juice, chopped parsley leaves, garlic and breadcrumbs, 1 tbsp oil and season. Open the mussel shells fully, pull apart and discard the empty half. Throw away any that won’t open.
Put the mussels attached to the half shells onto a baking tray, mussel-side up. Scatter the crumbs over them and grill for 1 minute until the crumbs are golden and crunchy. Serve with more lemon to squeeze over.
