Creamy turkey, broad bean and leek tagliatelle

Method

1. Melt the butter in a large, non-stick frying pan over a medium heat. Add the leeks and cook, stirring, for 5 minutes, until softened. Stir in the leaves from the thyme sprigs and mascarpone, let it bubble, then turn the heat to low. Cook for 10 minutes to thicken slightly.
2. Meanwhile, cook the pasta in a large pan of salted boiling water until al dente. Drain the pasta, reserving some cooking water, then return the pasta to the pan.
3. While the pasta is cooking, season the turkey, then put on a griddle pan over a medium heat for 8 minutes, turning halfway, until cooked through. Leave for a few minutes to rest, then slice each fillet diagonally.
4. Add some of the pasta water to the sauce to loosen, and bring back to a simmer. Add the beans and cook until tender. Stir in any turkey juices and season. Mix the sauce into the pasta, then divide between plates. Top with turkey slices and a few extra thyme sprigs.
