From The Art of Simple Food by Alice Waters:
Warm a heavy-bottomed pan. Add:
-3 T. olive oil
-1 medium onion, thinly sliced
-1 leek, white and light green parts, sliced
-pinch of salt
Cover and cook until soft but not brown. Add water to keep from browning if necessary.
-2 garlic cloves, peeled and sliced or crushed
Cook for about two minutes, then add:
-2 lbs. ripe tomatoes, washed, cored and sliced.. or two cans of good quality diced tomatoes.
-1 scant T. white rice
-large pinch of salt
-1/2 bay leaf
-1 small sprig of savory, thyme or basil
Cook over medium heat, stirring occasionally, until the tomatoes fall apart. Add:
-1 cup water or broth
-1 T. olive oil or butter
Continue cooking for another ten minutes, until the rice is tender. Remove the herb sprig. Blend until smooth. Taste for salt. Add more water if the soup is too thick.
-Garnish with mint or croutons, or with torn basil or finely cut chives and olive oil
