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?

Gregg and Chris are with a family whose weekly food shopping spend is out of control. The brand-loving Warners from Stratford-upon-Avon have a large family and an enormous food bill, but with a home renovation underway, every penny counts.

With four children and limited cooking skills, Hannah and Tim rely on pre-prepared food, whilst Hannah believes that if something is more expensive it must be better. Gregg and Chris secretly watch as they shop and see that they are being seduced by nice packaging and 2-for-1 deals, both classic shopping mistakes. However, when their spend is totalled up and they're confronted with the 17 receipts from the week before they are ready to change their ways!

Gregg and Chris make the food swaps that will hopefully save them money and all labels are removed. Yogurts are a family favourite, but is it worth paying for a top brand? Gregg visits a dairy to find out what the differences really are. The Warners have replaced their weekly takeaway with a supermarket one, but what goes into these ready meals? Chris is in the development kitchen of a factory, and is surprised by what he finds out. And dietician Lucy Jones reveals the shocking difference in the amount of sugar in jars of tomato pasta sauce.

This family have been a serious challenge for Gregg and Chris with Hannah convinced she would be able to tell a cheaper brand, but was her shock discovery when all is revealed enough to convince them they can eat well for less?

Gregg and Chris have their work cut out for them with the Booth family in Lancashire. Mum Jenny claims to always shop with a list and tries to be cautious, stocking up on buy-one-get-one-free deals. Dad Howerd's impulsive purchases mean that the food bill mounts up. They want to save £40 a week on food to afford a much-needed home extension.

Gregg and Chris get to work, secretly watching the Booths in the supermarket as they pile their trolley high, no lists or meal plans in sight. Considering the epic food shop, they expect to find the cupboards bare at home - but they find over £1,000 worth of food stockpiled in the kitchen.

After the Booths get a reality check about how much they are actually spending, all of their food labels are removed and some of their favourite products are swapped to see if they really like their brands as much as they think they do. The Booths love their sausages, so Chris heads to a sausage factory to see what the difference is between the mass-produced ones and ones from the butcher. Gregg investigates orange juice to see whether it's actually worth spending money on top-priced premium juice over concentrate.

The Booths' trial is over and they will only save if they accept enough of Gregg and Chris's swaps. Have they succeeded in changing the way this family shop forever?

We spend £1.2 billion a week on food - over £50 per household. Prices are rising, and we've got less money in our pockets. So in these cash-strapped times, can you get great value for money without compromising on quality?

Gregg Wallace (MasterChef) and award-winning greengrocer Chris Bavin are going head to head to uncover whether you should spend or whether you can save your pennies when it comes to buying food.

They're out to create two very different versions of the classic British dish - fish and chips. Gregg is seeking out high-end ingredients to prove you get what you pay for, and Chris is looking for a low-cost alternative that he hopes will taste just as good.

To test their theories, the boys brave stormy Norwegian seas to catch cod, take to the kitchen to create their own ketchup and even slip into lycra.

But in the end it's the great British public who decide in the final taste test. Whose version of fish and chips will win out - Gregg's high-end or Chris's great value? Is it worth splashing your cash when it comes to fish and chips?

The boys also hit Britain's streets to test other family favourite foods on the general public, with some surprising results... meaning we'll soon find out whether you really can Eat Well for Less.
