Watercress Soup

Watercress is one of the truly great radiant foods. It's hugely antioxidant, especially protective against lung cancer, and rich in iron, which makes it a key to inner beauty.

1 tbsp. olive oil
1 medium onion, finely chopped
2 cloves garlic, finely chopped
3 bunches watercress, with stems
1 quart vegetable stock
3/4 cup plus tbsp. plain yogurt with live bacteria

Heat the oil in a large saucepan and sauté the onion gently until soft. Add the garlic and continue to cook for 2 minutes. Add the watercress and continue to cook gently until it wilts. Add the stock and simmer for about 10 minutes. Transfer to a blender or food processor and whiz until smooth. Serve hot or cold with a swirl of yogurt in each bowl.
