This is a dish I had in Naples. Asciutta in Italian refers to pasta with sauce as opposed to soup, and this is similar to the classic pasta and bean soup except that it is prepared as a sauce.
Peel and finely chop the onion. Peel and finely dice enough carrot to measure about ¼cup. Peel the back of the celery to remove the tough strings and finely chop enough to measure about ¼cup.</
