Sauté minced garlic briefly in 1 tsp oil over medium heat. Add shredded chicken, soy sauce, and sesame oil; warm through. Combine with cabbage, carrot, bell pepper, bean sprouts, cilantro, and green onions in a bowl. Season with salt and pepper.
Dip rice paper in warm water 5–8 seconds until pliable. Lay flat, add a modest amount of filling near the edge, fold bottom over, fold in sides, and roll tightly. Seal edge with a dab of water and keep rolls covered with a damp towel.
Use wheat/egg wrappers or double-wrap rice papers. Place filling, fold and seal with water or egg wash. Heat oil to 350°F (175°C) and fry rolls in batches 2–3 minutes per side until golden. Drain on paper towels.
Whisk hoisin, soy sauce, rice vinegar, sriracha (if using), and sesame oil. Garnish with chopped peanuts.
Notes
Fresh rice paper rolls are best eaten within a few hours; store covered in the fridge.
Reheat fried rolls in a hot oven to bring back crispiness.
Use rotisserie chicken to save time, or swap protein for shrimp, pork, or tofu.
