It's the ultimate 'East meets West' fusion food.
When you really think about it, the sushi-burger combo seemed inevitable given Australia's obsession with Japanese cuisine and American-style burgers.
The dish involves making 'buns' of rice, and filling it with your meat, fish or veg of choice, slathered in a delicious sauce.
