In the final episode of the series we meet the Wilkinsons in North London, a family of fifteen whose food spend is a whopping £632 a week.
Aside from their 13 children, eating different meals in multiple shifts is sending their food bill sky high. Matt will be cooking the family a tasty chicken in tarragon sauce with hasselback potatoes for just 90p per person, as well as helping tackle lunchboxes and party food, while Susanna will be finding out how our shopping habits are changing and putting the country's favourite condiment to the super cheap taste test.
