Challenge #47 - cook something that costs less than £1

It's totally Wednesday, right?
* guilty expression *
* cough *
This week's challenge is to cook something that costs less than £1. That's US$1.34, AUS$1.77, and other currencies can be found here. I'm going on the honour system, but if you want to post a photo of the receipt you can :)
