Chinese Rice Crepes
The crepe part is pretty quick to make if you have a partner in crime. My mom uses 1/2 tapioca flour and 1/2 rice flour and some water to make the batter I believe.
As for the filling, she uses:
ground meat (pork), minced woodear mushrooms, minced onions, minced shittake, those really small dehydrated shrimps. Cook the onions till brown, add in the shittake, woodear, minced shrimp, and some soy sauce, cook until everything's tender. Add in the ground meat, break it up and cook until the meat is done. Set aside to use as filling.
Is this what you had in mind? They are rice sheets that are steamed and then cut into small squares and filled with any number of fillings. I have made them with a beef and orange filling, chicken and veggies and a shrimp filling. The recipe looks more difficult than it is. There are some good recipes for rice rolls in Ellen Blonder's Dim Sum book.
