Jamie Oliver and Jimmy Doherty are joined by Hollywood star Danny DeVito, who puts on his apron and cooks for the diners at the end-of-the-pier cafe in Southend. In honour of their guest's Italian roots, the boys have tracked down the village in Italy where Danny's grandparents lived before emigrating to the USA. Having sourced the ingredients from the village itself, Jamie and Jimmy take Danny down memory lane preparing the regional dish strachinatta con la mollica. Jamie makes a Korean-inspired roast chicken, with slaw and coconut buns. Jimmy's got a smoking hot DIY build to help a PE teacher cook up an Indian feast. And the boys head back to school to campaign for the Health School Rating scheme, which helps schools deliver healthy meals, health education and fitness.

Jamie Oliver and Jimmy Doherty kick off the new year with their first ever all-vegan menu, joined in the cafe by the straight man of comedy, Romesh Ranganathan. Embracing the spirit of Veganuary, Jamie and Jimmy set out to prove that vegan food can be so delicious that you won't even miss the meat. Romesh admits that the only thing he misses since he became vegan is a truly indulgent lasagne, complete with melting cheese and all the comforts of home, so Jamie takes up the challenge to reunite Romesh with his favourite dish. Jimmy's creative skills are put to good use when he builds a cold press to help a 16-year-old DIY enthusiast who wants to find a solution to fallen apples. And the boys visit the world's first fully vegan football stadium.
