Prepare all ingredients by washing and cutting as needed.
Soak one rice paper sheet in warm water for 10-15 seconds until pliable.
Place the softened rice paper on a clean surface.
Layer a few lettuce leaves on the lower third of the rice paper.
Add a small amount of vermicelli noodles on top of the lettuce.
Place shrimp, carrot, cucumber, and fresh herbs on the noodles.
Fold the sides of the rice paper over the filling.
Roll the rice paper from the bottom up, tucking in the filling as you go.
Repeat the process with the remaining rice paper sheets and filling.
Serve the rolls with soy sauce or hoisin sauce for dipping.
