Denver, CO, August 11, 2026 —
A popular street food, sometimes called the “world’s oldest sandwich” and described as a “Chinese hamburger,” is gaining attention in Denver. The Westword newspaper recently highlighted the roujiamo, detailing its presence in the city.
The roujiamo consists of a piece of slow-cooked, shredded meat, typically pork or lamb, stuffed into a baked flatbread bun. Its origins are traced back to China, with some historical accounts suggesting it dates back over a thousand years, making it a contender for the title of the world’s oldest sandwich.
Westword’s reporting points to specific locations within Denver where residents can experience this ancient culinary offering. The exact details regarding the eateries and their roujiamo offerings were featured in the article.
The sandwich’s description as a “Chinese hamburger” draws a parallel to the familiar Western fast-food staple, likely due to its handheld format and meat-filled nature. However, the preparation methods and flavor profiles of the roujiamo are distinctly traditional Chinese.
Further information regarding the specific establishments serving roujiamo in Denver and any unique aspects of their preparation can be found in the Westword article.
