Head teachers in England are being urged to ban packed lunches to increase the take-up of school dinners and promote healthy eating.
A government-commissioned school food review by two founders of the Leon restaurant chain says take-up is low at 43% despite huge quality improvements.
The authors of the School Food Plan say packed lunches are nearly always less nutritious than a cooked meal.
Petchey Academy in Hackney, London, is one school which has already banned packed lunches in favour of what it says are healthier, more nutritious school meals.
