Should schools scrap hot meals and require all pupils to bring packed lunches?

UK schools provide meals to over 3 million pupils daily, with free school meals for all infants and disadvantaged older children funded by government. Many meals are now reheated processed food rather than cooked from scratch, prompting criticism of nutritional quality and rising childhood obesity. Proposals to replace them with packed lunches eaten outdoors raise questions about cost, equity, supervision and weather resilience.
