I filled the rice paper wrappers with shrimp, lettuce, basil and rice vermicelli and served the rolls with peanut dipping sauce. I used a bagged lettuce mix that had some herbs already in it. The recipes I looked up said to add mint and cilantro as well. I'll save that for next time.
The rice papers come in a package as brittle sheets. When you soak them in warm water for a few seconds they soften up and behave like saran wrap. If you're not careful they'll start to cling up and stick to themselves.
The technique is to layer the fillings on one-third of the wrapper and then just roll it up like a burrito.
