01 - Cook rice vermicelli noodles according to package instructions, rinse thoroughly with cold water, and drain well. Julienne the carrot and cucumber into thin strips. Wash, dry, and tear lettuce leaves to appropriate sizes. Pat herbs dry and remove tough stems.
02 - Fill a large shallow dish with warm water. Submerge one rice paper wrapper for 5-8 seconds until pliable but not mushy. Lay flat on a clean, damp kitchen towel, smoothing out any wrinkles.
03 - Position 2 shrimp halves cut-side up, 2 inches from the bottom edge. Layer with a small portion of noodles, julienned carrot, cucumber strips, lettuce leaf, and an assortment of mint, cilantro, and basil leaves.
04 - Fold the bottom edge over the filling tightly. Fold in both sides toward the center, then continue rolling forward into a compact cylinder. Place seam-side down on a serving plate. Repeat with remaining wrappers and filling.
05 - Whisk together peanut butter, soy sauce, hoisin sauce, sriracha, vinegar, and honey in a small bowl until smooth. Gradually incorporate warm water, 1 tablespoon at a time, until reaching a dippable consistency similar to heavy cream.
06 - Arrange spring rolls on a serving platter with the peanut sauce alongside. For best results, serve immediately while wrappers remain fresh and vegetables retain their crunch.
