You need:
- 5 courgettes (cut into not too small chunks. We peel them only because the children prefer this not to be 'too green' but if you do not mind the colour then leave some or all of the skin in)
- 2 leaks, cut into not too thin slices
- a table spoon of oil
- 500 ml of boiling water (you can alter the amount of water depending on how thick you like this soup to be)
- salt
Heat the oil in a deep pan (under high heat). Add the leaks and fry for 5 minutes, then add the courgettes and the salt and fry for another five minutes. Then add the water, reduce the heat and simmer for 15 minutes. Finally blend the soup with a hand held blender (or in a food processor). Serve on its own or with parmesan cheese.
