courgette soup

or "insert vegetable here" soup.

Two medium sized courgettes,
a big onion,
a meduim sized potato,
150ml cream (18%)
pinch of ground pepper,
1.5 teaspoons of salt,
2 glasses of water

chop everything except the water. The potato is best thinly sliced.
In a large saucepan, fry the onions over a low heat in a little oil, for about 5 minutes. Add the other vegetables, mix around, fry for a couple of mins, then add the water, salt and pepper. The water shouldn´t entirely cover the vegetables.
Bring to the boil, then lower the heat and simmer for 15 mins.
Assuming everything is really soft, take of the heat, and carefully blend the mixture with a blending thingy. Add the cream, while blending, or stirring at the same time.
Yasta.

The onion/potato/water combo can be mixed with any vegetable I reckon, to make a soup (works with pumpkin and leek, anyway).
