Soak rice vermicelli noodles in hot water for 10 minutes until softened, then drain.
Prepare all vegetables: julienne carrots and cucumber, and wash lettuce leaves.
Fill a shallow dish with warm water and dip one rice paper wrapper for about 10 seconds to soften.
Lay the softened wrapper flat on a clean surface.
Add a small amount of vermicelli noodles, shrimp (or tofu), and a few pieces of each vegetable and herb.
Fold the sides of the wrapper over the filling.
Carefully roll from the bottom up, tucking the filling in as you roll.
Repeat with remaining wrappers and filling ingredients.
Serve with dipping sauce on the side.
Enjoy your fresh and colorful spring rolls!
