For the Salad Rolls: Fill a large shallow dish with warm water. Dip one rice paper wrapper into the water for about 10-15 seconds until it becomes soft and pliable. Lay it flat on a clean surface.
- Assemble the rolls: In the center of the rice paper, place a small handful of rice noodles, a few pieces of lettuce, cucumber, bell pepper, avocado slices (if using), and a few shrimp. Add a few sprigs of cilantro and mint leaves.
- Roll the wraps: Fold in the sides of the rice paper and roll it up tightly, making sure everything is securely wrapped inside. Repeat with the remaining ingredients.
- For the Peanut Sauce: In a small bowl, whisk together peanut butter, soy sauce, rice vinegar, honey, sesame oil, garlic, and chili paste (if using). Add water to adjust the consistency.
- Serve: Serve the rolls immediately with a side of peanut sauce for dipping. Garnish with fresh herbs or crushed peanuts if desired.
