Run a sheet of rice paper under warm water for a few seconds, you can just run it under the tap or fill a bowl with warm water. Lay it on a clean working surface, it will be firm, but will soften quickly. Lay a few slices of each ingredients on top, and when the rice paper is softened you can roll it all up like a burrito. Repeat until all of your fillings are used up.
In the meantime make the peanut sauce by combining everything in a bowl.
