Heat 25 g Butter in a large pan and add 2 Shallots, 200 g Chestnut mushrooms, 2 Garlic cloves and 1 teaspoon Fresh thyme leaves. Cook until softened, about 3-4 minutes.
Add 1 tablespoon Plain flour and stir it in.
Gradually pour in 250 ml Chicken stock, a little at a time, stirring each time. Bring to the boil and then reduce to a simmer.
Add 200 ml Reduced fat crème fraîche, 100 g Sweetcorn, 15 g Parmesan, 500 g Leftover turkey, 1 pinch Sea salt and 1 pinch Ground black pepper.
Give it all a really god mix and simmer for 5 minutes.
Serve on top of pasta (or rice, mash, etc.) and garnish with chopped parsley (optional).
Notes
A little bit of fresh lemon juice and zest really freshens up the dish. Add just before serving.
Make sure to simmer the sauce gently, especially after the turkey has gone in, because you don't want the turkey to overcook and become dry.
You can adjust the thickness of the sauce if needed. If it is too thick, then add some stock to thin it out. If you need to thicken it, then you can add a cornstarch slurry.
