Prepare the Sauce: In a small bowl, whisk together hoisin sauce, peanut butter, soy sauce, rice vinegar, honey, sesame oil, and sriracha (if using). Add warm water a little at a time to reach a smooth, pourable consistency. Set aside.
Cook the Shrimp: Heat olive or sesame oil in a skillet over medium-high heat. Season shrimp with salt and pepper. Cook shrimp 2–3 minutes per side until pink and opaque. Remove from heat.
Prepare the Vegetables: While shrimp cooks, shred carrots, slice bell pepper, chop cucumber, and green onions.
Assemble the Wraps: Place a few shrimp in the center of a lettuce leaf. Top with shredded vegetables. Drizzle hoisin peanut sauce over the top.
Serve: Arrange wraps on a platter. Serve immediately. Optionally garnish with sesame seeds or extra green
