A crumb from Rome, Italy

Dino Impagliazzo, 90, is a master chef and makes delicious vegetable soup, but most of his "customers" can even afford to buy a bread stick. He is known as Rome's "chef of the poor." Three days a week, he and other volunteers make the rounds to food markets and bakeries for contributions from retailers who help him live his dream of feeding the homeless.

Volunteers help cook the food and serve it in several places in the city, mostly near train stations. "We try to involve more and more people so that Rome becomes a city where people can love each other," he says. On Saturday nights, they set up under a portico outside St. Peter's Square to feed the growing number of homeless who sleep in the area, near where Pope Francis has also opened medical and bathing facilities for them.
