A food festival, titled 'Small Change, Big Difference' has been encouraging Londoners to reduce their waste and eat more healthily.
The campaign aims to make a big difference to the public's health, pockets and the planet.
The Sustainable Food Fest at Mercato Metropolitano featured award-winning Pan-Indian Chef Cyrus Todiwala.
He welcomed members of the public to join him for a cooking demonstration, using the top 10 household wasted foods, providing tips and tricks for creatively re-using food.
It's reported 900,000 tonnes of food go to waste from London homes every year. The number one wasted food is potatoes with a shocking 700,000 tonnes going to waste every year.
