Potatoes, basil, Parmesan, Pecorino and pine nuts create a delicate pesto-flavoured filling for courgettes. The stuffed courgettes are topped with cheesy breadcrumbs and baked until golden on top. Serve with a green salad for a light evening meal.
Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
