TV and radio presenter Rickie Haywood-Williams, legendary Motown singer Martha Reeves, Olympic gold medal-winning long jumper Greg Rutherford, actress Elizabeth Bourgine and heavyweight boxer Dillian Whyte take part, as the competition hosted by John Torode and Gregg Wallace continues. The first challenge for the five hopefuls is an Invention Test - the infamous test of imagination and creativity. The contestants are all given a mincer and a burger press and are tasked with making just one dish - a burger and fries - of their own design. Ingredients to choose from include tuna, mackerel, beef chuck, pork belly, lamb shoulder and turkey breast.
