Gregg Wallace and greengrocer Chris Bavin help families across the UK sort food fact from fiction and eat well for less. Gregg and Chris head to Wandsworth in south London to meet dental nurse Sheena King and her daughter Nila. Work pressures mean that Sheena's go-to is prepacked convience food, as well as organic produce, which she believes tastes better than non-organic food. Sheena never makes a shopping list, and spends on average three times more than the national average on the weekly shop, and since Nila is a picky eater so Sheena ends up cooking two separate meals everytime. Can Gregg and Chris curb Sheena's spending and show her an alternative way of shopping that will satisfy her expensive tastes, Nila's eating habits and save them money along the way?
