Rou Jia Mo 肉夹馍 is perhaps one of the cheapest and most delicious types of Chinese street food. The most common English name is “Chinese hamburger.” Basically, its just meat between two pieces of bread. The most traditional of these involve stewed pork that his been finely chopped and stuffed into a small type of Chinese flat bread. Currently, there are many different varieties, but the sandwich originated in Xian. The history of the flatbread and stewing of pork involved suggest that this Xian snack actually out dates all other sandwiches in the world.
Many of my Chinese friends become shocked when I often joke that it’s the most “American” thing in Chinese cuisine. Sandwiches are a huge part of American food, especially in places like Philadelphia, New Jersey, and New York City. Even more, in the southern part of the USA, a “pulled pork” sandwich is a common thing sold along roads. The process is different, and the difference being “pulled pork” is slowly roasted and the meat fibers are tugged apart and separated either by hand or with knives. No matter whether you are in China or the USA, you are still eating shreds of pork between two pieces of bread. By the way, the best pulled pork sandwich in Changzhou is actually at Daniel’s Irish Pub in Xinbei.
As for rou jia mo, it’s a very common thing in Changzhou if you know how to look for it. Part of it is just being able to spot 肉夹馍 on kiosk signs. As fast food when in a rush, it is far much cheaper than getting a sandwich at McDonalds, KFC, or Burger King.
