Boil water in a pot. Add glass noodle for 1-2 minutes until al dente (chewy). Drained and set aside.
Fill luke warm water into a plate. Soak Vietnamese spring roll skin into the water for 2-3 seconds until skin softens and easy to handle.
Remove the softened skin and flatten it on a plate or a clean surface.
Put half of the glass noodle, chicken meat, lettuce, carrot, sliced chillies, coriander and bean sprout in the middle of the skin. Leave about 2 inch of empty space around the filling.
Take the end of the skin carefully, wrap the filling both sides and roll tightly.
Repeat method 2-5 for the remaining of the spring rolls.
To make the sauce: Blend chilli (11/2) together with vinegar and lemon juice. Pour into a serving plate.
Serve Vietnamese Spring Roll together with the sauce.
