Chefs dish up surplus food from Olympic Village to Rio's hungry

As athletes have warmed up for the Rio Olympics 2016, dozens of chefs are preparing for a different kind of challenge: feeding the Brazilian host city's hungry with excess food from the Olympic Village.

Chefs David Hertz from Brazil and Italian Massimo Bottura, aided by more than 40 colleagues from around the world, aim to turn surplus food from the village in Rio de Janeiro into some 5,000 nutritious meals per day for those in need.

The initiative, RefettoRio Gastromotiva, follows a similar project, Refettorio Ambrosiano, launched by the two chefs during the Milan Expo in Italy last year.
