The toasted cheese sandwich, or toastie as it's more commonly known, has been enjoyed by generations around the world.
The dish is seemingly simple, generally containing cheese, potentially some ham, tomato and onion, or even a bit of spaghetti (here's looking at you, Bill).
But what if there was a better way to make a toastie, and ensure that your bread was always perfectly crispy, without having to use even a lick of butter?
According to Australian food writer Tristan Lutze, the trick is in using mayonnaise instead of butter on the outside of the bread, which could at least be a cheaper option at the moment.
