Gregg and Chris help the Stanton family from Maidstone, and for the first time ever they see a three-year-old help with the family food shop...

The Stantons are spontaneous shoppers, and a fear of the freezermeans that they are throwing away a lot of food and money every week. They're not alone - each year in the UK we throw away 7 million tonnes of food, the equivalent of six meals per family per week.

Mum Zoe and dad Dan need help and Gregg and Chris are at hand, but first they secretly watch their weekly shop with three-year-old Sophia to see where it's going wrong. As they go for the pre-chopped fruit and veg with no list in sight, Sophia decides she wants to get involved, with everything she points to going in the basket.

If the Stantons find it hard to say no it's for a very good reason: Sophia was diagnosed with leukaemia, but is now on the road to recovery and so the way they shop needs to change. Gregg and Chris get to work swapping some of their usual brands. Zoe is convinced that she will be able to tell if her favourite brand of baked bean has been swapped, but can the public really tell the difference when we do a taste test between premium brands and a supermarket's own?

Gregg and Chris show the Stantons how to make their freezer work for them, dispelling some of the myths about frozen food. Is it possible that frozen could be better than fresh? And family favourite chicken nuggets are under dietician Lucy Jones's microscope.

The Stanton family have been through a difficult time, but will Gregg and Chris's changes save them enough money get them the dream holiday they so deserve?
