Actor Sir Patrick Stewart; comedian and writer Shappi Khorsandi; medic Oscar Duke and charity worker Mischa Pearson join Libby Purves.

Mischa Pearson set up the Teapot Project in Ipswich, Suffolk. The charity collects good food from restaurants and supermarkets that would otherwise go to waste and distributes it to the local homeless through charities, youth hostels and churches. As a teenager Mischa was homeless for two years and spent time living in hostels before finding employment in the catering business. Around 4,000 people a month benefit from meals provided by the Teapot Project and there are plans to open a new café with an adjacent food boutique offering ''pay as you feel' produce in the heart of the town.
