Gregg Wallace and Chris Bavin are in Buckinghamshire with the Venter family. Fitness instructor Kim is on a mission to get her lorry-driving husband Martin eating healthily when he is not on the road. As a pescatarian she likes him to have meat-free dinners with no carbs. Kim and Martin have two sporty teenage boys who eat the opposite to them - protein-packed meaty meals with plenty of pasta or potatoes. So Kim is faced with cooking at least two meals every night. Not only is this time consuming, it is costly too. Can Gregg and Chris put an end to these habits and get the whole family eating vegetarian, protein-packed, nutritious meals together that would give them more money in their wallets for a family holiday?
