A fresh, summery pie that will make a tasty main attraction for any picnic. Cut into slices for packed lunches
A sheet of greaseproof paper or baking parchment placed over the surface of the leeks as they cook will help them soften in their own steam rather than frying. Don’t skip the salting of the courgettes as this will leave you with a wet filling.
