Cook the rice vermicelli noodles according to package directions, rinse with cold water, and prepare all vegetables, herbs, and shrimp before assembling the rolls so everything is ready for quick rolling.
Whisk together peanut butter, soy sauce, rice vinegar, lime juice, honey, sesame oil, warm water, and optional sriracha until smooth and creamy for the dipping sauce.
Dip one rice paper wrapper into warm water for about 10–15 seconds until flexible, then place it on a damp towel or cutting board to continue softening gently.
Add lettuce, noodles, vegetables, avocado, herbs, and shrimp into the center of the wrapper while leaving space around the edges for folding and sealing.
Fold the bottom edge over the filling, tuck in the sides, and roll tightly upward until fully sealed. Repeat with the remaining wrappers and fillings.
Arrange the finished rice paper rolls on a serving platter and serve immediately with peanut dipping sauce while the vegetables remain crisp and fresh.
