If you have lots of zucchini (courgette or squash), this is a simple recipe to turn them into a lovely light soup. Here's the trick: make sure you cook both the zucchini and the leeks for long enough first so they're quite soft before you puree.

1. Slice the zucchini and leek thinly. Place in a saucepan with the chicken stock.
2. Bring to the boil, then reduce heat and simmer for about 5-7 minutes or until soft. Cool slightly and puree in a food processor or with a hand-held stick blender.
3. Return to the saucepan, add parsley and heat through. Stir through the yoghurt and pepper without boiling. Serve sprinkled with Parmesan and topped with a few toasted croutons if you like.
