In the last four years the number of vegans in the UK has more than quadrupled. Chef Simon Rimmer visits the home of the Meat Feast, Pizza Hut, to discover the challenges involved in creating their first fully vegan menu. And he hits the kitchen to demonstrate his trick of the restaurant trade: how to make the perfect glossy chocolate sauce for dessert. Simon also competes with Sophie Morgan to find the best deals for high street meals. With £35 each, they have to buy lunch, dinner and hot drinks for two. And with the government challenging restaurants to reduce the amount of sugar in their foods, reporter Adam Pearson takes to the street to find out if we can tell how much of the white stuff is in our desserts. Plus: food fad or permanent fixture? A Manchester family explores the trend that's bringing street food in from the cold: food halls.
