Stuffed Broiled Mussels

In a large pot, combine the wine, water, onion, parsley stems, and bay leaf. Cover and bring to a boil over medium heat. Add the mussels and steam until they open, 2 to 6 minutes. As the mussels open, transfer them to a large dish with a slotted spoon or tongs. Discard any mussels that don't open.
When the mussels are cool enough to handle, open each mussel and remove the upper shell. Using the tip of the shell, loosen the meat meat but leave it on the lower shell. Place the mussels in the lower shell on a rimmed baking sheet. Reserve the upper shells. Preheat the broiler.
In a medium bowl, combine the bread crumbs, minced parsley leaves, garlic, olive oil, and salt and pepper to taste. Sprinkle the bread crumb mixture over the mussel meat in each shell. Drizzle the lemon juice over the mussels.
Broil until the bread crumbs brown, 1 to 2 minutes. Don’t walk away! The bread crumbs burn easily. Serve immediately, either with tiny forks or with the reserved mussel shells to use as a scooping device.
