Preheat your oven to 170°C (340°F).
In a measuring jug, combine the dry white wine, white wine vinegar, mustard, port, and brandy. Set aside.
Place the chicken drumsticks, prosciutto, cherry tomatoes, shallots, bell pepper, sun-dried tomatoes, sun-dried peppers, and garlic in a large, ovenproof dish with a lid. Season generously with salt and pepper, and toss to mix the ingredients evenly.
Pour the prepared wine mixture over the chicken and vegetables, ensuring an even distribution. Drizzle with extra-virgin olive oil.
Cover the dish and cook for 1 hour, allowing the flavors to meld together.
After an hour, remove the lid and continue cooking for an additional 30 minutes, or until the chicken is golden brown and cooked through.
Once ready, sprinkle the dish with freshly chopped parsley and a touch of lemon zest before serving. This dish pairs wonderfully with rice or a light salad for a complete meal.
