In a deep, large, heavy pot over moderate heat, saute garlic and pancetta in extra-virgin olive oil for 3 minutes. Add onions and cook 1 or 2 minutes longer.
Add the greens and wilt them down to fit them all in the pot. Add beans, broth, and nutmeg, salt and pepper. Cook over moderate to medium-high heat for 12 minutes, or until greens are no longer bitter. Serve with shaved cheese, bread, and good red wine.
