Tumblr user nonomella is currently teaching in China. She made a PowerPoint of her students' reactions to "Regional/Iconic American Foods."
On her blog she started answering questions about the lesson, explaining that she chose stock photos that were really easy to identify and not anything like Chinese food.
She's currently teaching with CIEE, based in Suzhou.
The main takeaway from this is that it seems as though the beauty of key lime pie is universally recognized.
And that Chinese students are equally confused by the concept of a bowl made of bread full of soup that you can eat.
