Ribollita Soup

1. Drain canned tomatoes, reserving the liquid. Dice the tomatoes. Using a potato masher, mash half the beans into a paste (add a bit of broth, if desired, to make mashing the beans easier). Set the tomatoes and beans aside.

2. Heat 2 tablespoons oil in a Dutch oven over medium heat. Add leek and garlic; cook, stirring, until translucent and tender, 2 to 3 minutes. Do not brown. Season with 1/8 teaspoon pepper. Stir in carrots, celery and zucchini and the remaining 1 tablespoon oil; cook, stirring, until nearly tender, 3 to 5 minutes. Season with 1/8 teaspoon each salt and pepper.

3. When the carrots and celery are nearly tender, stir in kale (or chard) and cabbage. Cover and cook, stirring occasionally, until wilted, 4 to 6 minutes. Add potatoes, broth, water, the diced tomatoes and juice, the bean puree and whole beans, thyme and bay leaf. Bring to a simmer over medium heat. Season with celery seed, crushed red pepper and the remaining 1/4 teaspoon pepper and 1/8 teaspoon salt. Cover and cook, stirring occasionally and reducing the heat as necessary to maintain a gentle simmer, until all the vegetables are tender, 15 to 20 minutes.

Tips

Tip: To clean leeks, trim and discard green tops and white roots. Split leeks lengthwise and place in plenty of water. Swish the leeks in the water to release any sand or soil. Drain. Repeat until no grit remains.
