The Chiko roll, that most Australian of icons, was created when a Chinese takeaway owner, who sold food from a caravan outside of the Melbourne Cricket Ground (MCG), decided to package Chicken Chow Mein in a more convenient manner.

It was originally called a Chicken Chow Mein Roll, but the modern equivalent has too little chicken content to be legally called such, and thus 'Chicko' was born.

Speaking of Australian culinary innovation at sporting venues, has anyone mentioned the pie floater?
