01 - Submerge rice vermicelli noodles in hot water for 5-7 minutes until tender. Drain thoroughly and rinse under cold water to stop cooking. Set aside in a colander to remove excess moisture.
02 - Arrange all prepared ingredients on your work surface in separate piles: shrimp halves, lettuce leaves, mint, cilantro, basil, julienned carrots, cucumber strips, and cooked noodles. Having everything organized makes the rolling process efficient.
03 - Fill a large shallow bowl with warm water. Submerge one rice paper wrapper completely for 5-8 seconds until pliable but not mushy. Remove and lay flat on a clean, damp kitchen towel or cutting board.
04 - Position the wrapper with one corner pointing toward you. Place lettuce leaves on the bottom third, followed by small portions of noodles, carrot, cucumber, and herbs. Arrange 2-3 shrimp halves cut side up on top for visual appeal through the translucent wrapper.
05 - Fold the bottom edge over the filling tightly. Fold in both sides toward the center. Continue rolling forward from bottom to top, applying gentle pressure to create a tight cylinder. The wrapper will seal itself. Repeat until all ingredients are used, yielding 8 rolls.
06 - Combine peanut butter, hoisin sauce, soy sauce, lime juice, and sriracha in a small bowl. Whisk vigorously while gradually adding warm water until smooth and creamy. Adjust consistency with additional water if needed for a dipping consistency.
07 - Place spring rolls on a serving platter with the peanut dipping sauce alongside. For best texture and appearance, serve within 2 hours of preparation. If making ahead, cover rolls with a damp cloth to prevent drying out.
