I'll bet you can find one by using the filters in the search function -- try limiting a search to Chinese recipes that include bean curd rolls and oyster sauce. I'd like to see such a recipe, too, although I'm looking for beef with bean curd and scallions in oyster sauce. The two dishes sound similar. The beef with bean curd was a common dish on Chinese menus in San Francisco and I used to have it for lunch all the time when I lived there, but here in Kansas City I never see it on menus, so I'll have to make it for myself!
