In a large cast iron casserole, combine the wine and garlic and bring to a simmer. Add the mussels and cook, uncovered, until they begin to open, about 3 minutes. As they open, sprinkle aggressively with parsley and black pepper. Once they are fully opened, remove from heat, sprinkle lightly with salt, drizzle with olive oil and serve immediately.
