Cauliflower, Kale and White Bean Soup

1 cup dried white beans, such as cannellini or great northern, soaked overnight
2 tablespoons extra virgin olive oil
2-3 leeks, white and light green parts sliced (about 2 cups)
3 cloves garlic, chopped
¼ teaspoon crushed red pepper flakes
4 cups chopped kale leaves (about 1 medium bunch)
1 small head cauliflower, broken into florets
4 cups vegetable stock (recommend Imagine No Chicken broth)
2 cups water
2 cups bean cooking liquid, plus 1 more cup if needed
1 bay leaf
1 teaspoon salt
Freshly ground black pepper to taste
½ cup flat-leaf Italian parsley leaves

Drain the beans and put them in a pot with water to cover by two inches. Bring to a boil, then reduce heat and simmer until the beans are tender, about one hour. Drain, reserving cooking liquid.

Heat the olive oil over medium heat in a large pot or dutch oven.  Add the leeks and cook until very soft, about 10 minutes. Add the garlic and red pepper flakes, and cook for one minute more. Add the kale and cook, stirring, for five minutes.

Add the beans, cauliflower, stock, 2 cups of bean liquid, water, bay leaf, salt and pepper.  Bring to a boil, then reduce heat and simmer until the cauliflower is tender, about 12 minutes. Add the parsley. Remove the bay leaf.

Cool, then puree in a food processor until smooth. Add the extra cup of bean cooking liquid if it seems too thick. Return to the pot and reheat.

Serves 4-6
