Jamie's back with a new bee in his bonnet. After campaigning for better school meals for the nation's children, he's set to tackle what we're eating at home. And it's not pretty. "I've been to Soweto and seen kids in AIDS orphanages eat better than this," says a shocked and saddened Jamie. He's starting his campaign in Rotherham, a city of fast food junkies and set to become the fattest region in Britain. His mission, to teach mums the basics for healthy home cooking, get them to teach their friends and get the menfolk cooking too. Will Jamie's catering crusade take off or are his dreams just pie in the sky?
