Beef Green Paper

It sounds like you are trying to learn more about a food dish named "beef green paper" that you have seen in restaurants in the USA. However, I am not familiar with a dish by that exact name. It is possible that there may be a misunderstanding or miscommunication regarding the name of the dish.

One possibility is that you might be referring to a dish called "beef wrapped in lettuce" or "beef lettuce wraps," which is a popular dish in many Asian restaurants in the USA. In this dish, thin slices of beef are cooked and served with lettuce leaves, and diners can wrap the beef in the lettuce leaves and eat it like a wrap or taco.

Another possibility is that "green paper" might be a mistranslation or misunderstanding of the words "rice paper" or "spring roll wrapper," which are thin, translucent sheets made from rice flour or wheat flour that are commonly used to make Vietnamese or Thai-style spring rolls.

If you could provide more context or clarify the name of the dish, I would be happy to help you learn more about it!
