In 1986, Carlo Petrini and a group of friends threw a big pasta feed in Rome's storied Piazza di Spagna (the Spanish Steps).
The event was a protest against the opening of the first McDonald's in Italy. Out of that grew Slow Food, an organization that now includes 100,000 people in 150 countries, all committed to local food and the traditions associated with it. Buon gusto!
