Gregg Wallace and Chris Bavin help families across the UK sort food fact from fiction and eat well for less. They visit the Dye family in Bedford. Jon and Lisa Dye don't cook and while car part specialist Jon lives on a diet of convenience food and crisps, flight attendant Lisa has a sweet tooth. With Lisa often away with work, meal times are haphazard. They often miss meals and they rely on their microwave. This lack of organisation means their shopping bill comes in under the national average. Could this be the first time Gregg and Chris push a family's spending up in the hope of improving their health and nutrition?
