  • 2 large celery ribs, finely chopped

  • Add the water, beans, tomatoes, bay leaf and cheese rind, cover and bring to a boil.
  • Reduce the heat to low and simmer until the beans are tender, about 1 hour.
  • Meanwhile, in a medium saucepan of boiling salted water, cook the pasta until it is al dente.
  • Drain.
