Yotam Ottolenghi is an Israeli-English chef, restaurant owner and food writer who taught Britain to love vegetables.

He has published seven best-selling cookbooks inspired by his Middle Eastern upbringing in a German/Italian family and owns six restaurants and deli’s across London.

Since arriving in London over 20 years ago, Yotam Ottolenghi has made it his mission to help British people see vegetables as something other than a “necessary evil”. While not a vegetarian himself, his latest book 'Flavour' is entirely vegetable-focused.

This week on Ways to Change the World, he speaks with Krishnan about cultural appropriation and the politics of hummus.
