Put all the ingredients for the sauce in a bowl in sequence and stir them until a homogenous mixture forms. If the peanut butter won't fully dissolve, use a hand blender.
Chop the red cabbage, put it in boiling water, and then add the juice of half a lemon.
Remove the red cabbage and pour the still hot water over the glass noodles. The noodles don't need to be cooked further. Hot water is sufficient for soaking them. After about 10 minutes, take the dyed, softened noodles out of the water.
Dip the rice paper briefly in water to make it soft and flexible. Spread it out on your work surface. Cover a strip in the middle of the paper with a small lettuce leaf, a mint leaf, and individual strips of cucumber, pepper, carrot, avocado, and mango.
Cover the filling with a small portion of glass noodles. First fold the lower section of the rice paper and then the sides over the filling. The soft paper will stick to itself and hold the rolls together.
