3) Season with salt and ground black pepper to taste.
4) Add the vegetable stock, turn up the heat and bring back to the boil.
5) Put the lid on the pan and turn down the heat so that the sauce is simmering slowly. Cook for 15 minutes.

7) Drain off the pasta and pour it into an ovenproof casserole dish. Pour in the sauce and mix everything together well. Check for seasoning.
8) Sprinkle the top of the pasta with either the parmesan or breadcrumbs.
9) Put onto the middle shelf of a preheated oven at 220ºC.
10) Bake for 10 to 15 minutes, keeping an eye on it, until the top is golden brown.
