Lentil Soup with Cauliflower and Bacon

Ingredients

1. 6 slices bacon, cut crosswise into thin strips
2. 1 onion, chopped
3. 1 cup lentils
4. 2 teaspoons salt
5. 1/4 teaspoon fresh-ground black pepper
6. 1 1/2 teaspoons dried rosemary, crumbled
7. 1 bay leaf
8. 9 cups water
9. 1 small head cauliflower (about 1 1/2 pounds), cut into small florets (about 1 quart)
10. 1/3 cup chopped fresh parsley

1. In a large pot, cook the bacon strips until crisp. Remove the bacon with a slotted spoon and drain on paper towels. Discard all but 2 tablespoons of the bacon fat or, if there's less than 2 tablespoons, add enough olive oil to make up the amount.
2. Reduce the heat to moderately low. Add the onion to the pot and cook, stirring occasionally, until translucent, about 5 minutes.
3. Add the lentils, salt, pepper, rosemary, bay leaf, and water to the pot. Bring to a boil. Reduce the heat and simmer, partially covered, stirring occasionally, for 15 minutes. Add the cauliflower florets and simmer, stirring occasionally, until the cauliflower and lentils are tender, about 15 minutes longer. Remove the bay leaf.
4. Stir the parsley into the soup. Serve the soup topped with the bacon.
