In 3-quart saucepan, heat oil over medium heat. Add pancetta and cook about 3 minutes, stirring occasionally, until slightly crisp around edges. Add onion, carrot and celery. Cook about 5 minutes, stirring occasionally, until vegetables soften but do not brown. Add finely chopped garlic and cook 30 seconds, stirring constantly. Add broth, water, beans, tomatoes, tomato paste, anchovies, the cheese rind, bay leaves and rosemary; heat to boiling. (When you’ve used a piece of Parmesan cheese, save the rind in the freezer. If you don’t have a rind, you may want to sprinkle each serving with grated Parmesan cheese.) Reduce heat and simmer 30 minutes, stirring occasionally.
