Cook the noodles: Boil vermicelli for 2–3 minutes, rinse under cold water, and drain.
Prep your veggies: Julienne the carrot and cucumber. Wash and dry herbs.
Make the sauce: In a small bowl, whisk together all the peanut sauce ingredients until smooth. Add warm water until it’s creamy but not too thick.
Set up your rolling station: Have a bowl of warm water ready to dip the rice papers. Lay a damp towel or clean surface for rolling.
Soften the rice paper: Dip one wrapper into warm water for 4–5 seconds. Lay flat.
Fill the roll: Start with lettuce, then noodles, a few carrot and cucumber sticks, and herbs. Place two shrimp halves near the top edge for a clean finish.
Roll it up: Fold the sides inward, then roll tightly from the bottom like a burrito. Repeat for each roll.
Serve: Cut in half if you’d like and serve with peanut sauce.
