Celebrity MasterChef winner Nadia Sawalha is sent on a dramatic, colourful and tasty culinary journey through some of the best restaurants in Europe and beyond, by some of the best chefs in the UK. Nadia is challenged to recreate a famous chef's most memorable holiday meal in the same restaurant in which they originally ate it. She has just two days to slot into a working kitchen, learn the recipes and source the ingredients before then having to serve the meal to her mystery challenger. The twist? She doesn't know who she is cooking for until they walk through the restaurant door. Nadia finds herself in a beachside fish restaurant, a far cry from her Michelin-starred challenges. Will her culinary Achilles' heel finally be exposed? Operating a fish grill in the sweltering summer heat is a recipe for potential disaster as she fights with every type of fish the Mediterranean has to offer. She also gets to grips with prawns, clams and mussels while cooking cataplana, the regional classic of the Algarve, and makes the strange-looking angel hair dessert. She also has her work cut out as she attends the annual sardine festival and the regional shellfish festival - before serving up a fishy meal to one of the slipperiest mystery customers in the series. If she fancies herself as a fine chef, why is grilling a simple sardine so difficult?
