Place a rice paper on a rolling mat or a damp cloth. Layer with the following in order; a lettuce leaf, a little rice vermicelli (which will have been cooked in unsalted boiling water about 1 minute, then rinsed with cold water to remove excess starch), some herbs, some bean sprouts, a little pickled carrots and daikon, and topped with a piece of salmon. Fold the wrapper on the first third of its size, and repeat with the sides toward the centre so as to form a pocket, then roll tightly to create a roll.
