Summy, I am sorry that I didn't see your post earlier. I have been offline for a few days.
I hope you have managed to find something helpful by now. Your topic is not an easy one. Do your students have internet access? Can they do a google search for recipes?
You might have students find recipes and try them out. They could work together in groups to try cooking a recipe that they find in Google. Then they can write up how they did it and share the results with the class. Would class members be able to follow their instructions to cook the same food? Grammar could focus on giving instructions or description. They could also do a comparison/contrast - how this food is similar to or different from some common Chinese food.
You might have the class take recipes they find online and write their own cookbook. They would not copy recipes that they find, but would adapt them to the way they cook at home. The cookbook could include an introduction that would highlight the differences between Chinese and international cooking methods.
Hope you find some of these ramblings helpful.
Blessings <>< Lynn
