These can be served with sweet chilli sauce or a combination of one part hoisin sauce, one part fresh peanut butter, 1/2 part lime juice and some chopped fresh chilli. And they can also be made with tofu, as described above, or with prawns (shrimp).
To incorporate prawns, omit tofu and lay three peeled and deveined cooked prawns over vermicelli mix before folding the rolls. Use with a dipping sauce of your choice.
