Your tummy is grumbling for some pizza, but what kind? Now, you don't have to decide.

Pizza Hut is testing something called a Subconscious Menu, in which customers' eye movements are tracked to see which ingredients they focus on for the longest amount of time. The idea is that the longer they look at a certain ingredient the more likely it is their subconscious wants it.

Pizza Hut is currently only offering the menu in Britain because if there's one thing the British know, it's food, right?

Check out a commercial to see the menu in action, below.
