Happiness is a well-packed lunchbox

Want to save another £120 towards Christmas? Open the fridge and concoct packed lunch from leftovers. That's the latest idea from Love Food Hate Waste campaigners, who claim that we chuck out about the same amount of lunch ingredients that we pay an average of £3.33 for each day.

Sales of lunchboxes are soaring, but only a third of us actually bother going to the trouble. I have suffered inedible pub grub, unspeakable meat sandwiches and dodgy sushi filming on location, so nowadays I always take my own lunch, even if it means hiding the huge amount in the container from nosey onlookers. Home-made does not necessarily mean health-conscious. And for how long can you keep a pork pie in the fridge?
