Leek, mushroom and blue cheese pie

This is one of those dishes that you throw together from what's in the fridge - a few leeks, half a packet of filo pastry, some blue cheese - and it turns out to be unexpectedly delicious.

Like my previous recipe, leeks are the star of the show. I think these two dishes show what a versatile vegetable leeks are - from a light and elegant salad to rich and hearty pie.

Filo pastry is much lower in fat than other types of  pastry, so you can enjoy this pie, perhaps with some more vegetables on the side, and feel relatively virtuous at the same time.
