We all know that munching on more vegetables is good for us, but let's be honest, we're all guilty of buying veggies and leaving them to rot in the back of our fridges because we forget we ever put them there.
But according to a cooking expert, there's actually an easy way to make your salad last for up to four days longer than normal - and it's free to do if you happen to own a SodaStream.
SodaStream machines are traditionally used for making carbonated drinks, as they pump carbon dioxide into a liquid to make it fizzy. But if you put a few pumps of carbon dioxide into a bag of lettuce and seal it shut, it will help keep your greens fresh for up to nine days - as opposed to the usual five days your salad would last.
