Place approximately 1/4 cup of the chicken mixture into the center of the lavash bread, and roll into a sandwich. Also, I usually add a spoon of leftover chicken broth for added moisture, but you don’t have to. Place in a jelly roll pan, or cookie sheet. Repeat for the rest of the lavash bread. If you are using Iranian or saj bread, wrap it more like a burrito, by folding the sides in. You also don’t need 10 sheets. Just 4-5 are plenty since they are so large. You can just cut the sandwiches when serving them.
