Cabbage-and-Kale Soup with Farro

Preheat the oven to 350°. In an enameled cast-iron casserole, heat the oil. Add the pancetta and cook over moderate heat until the fat is rendered, 3 to 4 minutes. Add the onion and garlic and cook until softened, 5 minutes. Add the anchovy paste and cook for 30 seconds. Add the farro and cook, stirring, for 3 minutes. Add the cabbage and kale and cook, stirring, until just wilted.

Add the chicken stock, water, thyme and rosemary sprigs and cheese rind and bring to a simmer. Cover the soup, transfer to the oven and cook for about 1 hour, until the farro and greens are tender. Alternatively, simmer the soup over moderate heat for 1 hour. Season the soup with salt and pepper. Transfer the soup to bowls, garnish the soup with the parsley and grated cheese and serve.
