Ribollita Tuscan Twice Boiled Soup

In a large heavy-bottomed pot or Dutch oven, heat 3 tablespoons of olive oil over medium heat. Add the chopped onion, carrots, and celery. Cook gently, stirring occasionally, until the vegetables soften, about 8-10 minutes. This forms the flavor base.

Stir in the minced garlic and cook for another 1 minute until fragrant. Add the chopped Tuscan kale and sliced green cabbage. Cook, stirring, until the greens begin to wilt and reduce in volume, which takes about 5-7 minutes.

Pour in the canned chopped tomatoes and their juices, along with the rinsed and drained cannellini beans. Add the vegetable broth. Bring the mixture to a gentle boil, then reduce the heat to low, cover, and simmer for at least 30 minutes to allow the flavors to meld beautifully.

Remove the pot from the heat. Stir in the torn pieces of day-old rustic bread. Gently push the bread down into the soup so it can absorb the liquid. Let it sit, covered, for at least 15-20 minutes, or longer, allowing the bread to fully soften and thicken the soup. This is the 'first boil' concept where the soup rests and flavors deepen.

Place the pot back on medium-low heat. Gently stir the soup, breaking up any large bread chunks. Bring it back to a gentle simmer, stirring frequently to prevent sticking, for another 10 minutes. This is the 'second boil', ensuring the soup is hot and the consistency is perfect. Season generously with salt and freshly ground black pepper to taste.

Ladle the hot Ribollita into bowls. Drizzle each serving with a generous amount of fresh extra virgin olive oil and, if desired, sprinkle with grated Parmesan cheese. Serve immediately, perhaps with an extra slice of crusty bread on the side for dipping.
