Preheat the oven on 180C/360F/Gas 4.
Cook the pasta in salted boiling water until al dente.
Drain the pasta and place back into the saucepan. Add in the butter and the cheeses excluding half of the parmesan.
Mix well and then add in the milk. Return the saucepan to a low heat and stir until you get a creamy-textured sauce.
Add the turkey, the stuffing and the flatleaf parsley and season, to taste, with salt and freshly ground black pepper.
Transfer the pasta mixture to a large baking tray. Sprinkle over the remaining parmesan cheese and place in a pre-heated oven to bake for 15 minutes, until the top is golden and crispy.
Remove from the oven and serve immediately.
