Preheat the oven to 200°C/gas mark 6. Put the swede cubes into a roasting dish, trickle over the oil and season. Roast for 35-40 minutes, until soft and golden brown.
When the swede is almost done, put a pan of water on to boil for the pasta. Meanwhile, heat the butter in a large, wide saucepan over a low heat. Add the onion, chilli and garlic and sweat for 8-10 minutes, until the onion is soft but not coloured. Then turn up the heat to medium and add the swede tops. Season and stir for 1-2 minutes until wilted.
While the veg are sweating, salt the boiling water and cook the pasta according to packet instructions.
When the swede is ready, add it to the pan of onions and wilted greens. Drain the pasta and stir it in, with a slosh of extra-virgin oil, and more salt and pepper if needed. Toss together. Serve straight away, in warmed bowls, topped with a generous sprinkling of cheese.
