I'd like to make a chocolate dessert sushi but I'm stuck trying to come up with a substitute for nori *or* rice paper.  I know some people like to use plastic chocolate like in this [question][1].

However I'd like to do something different to compliment the chocolate on the inside of the roll.  Nori and ricepaper don't seem like they would work well for a dessert. 

So if anyone has an idea, I'd love to hear it. 

As a *bonus*, has anyone tried using something other than coco rice krispies for crunchy?  They tend to get soggy and lose their crunch if you wait too long to eat them.
