This is a traditional Ligurian dish that is usually made with potatoes, green beans and baby broad beans. Here, broccoli and courgettes boost the green vegetable content. The pesto sauce used to dress the pasta and vegetables is lighter than most, but still packs a wonderful flavoursome punch.
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.
