Use up blue cheese
Crumble 50g Stilton, Dolcelatte or Roquefort into the sauce, instead of the Parmesan. Spoon the pasta into the dish, then top with 4 trimmed field mushrooms, gills facing upwards, instead of the crumbs. Drizzle with a little oil, season, then top with a little more blue cheese. Bake as before.
