01 - Season the chicken breast evenly with salt and black pepper on both sides. Heat sesame oil in a skillet over medium heat. Place chicken in the pan and cook for 4–5 minutes per side until cooked through and internal temperature reaches 165°F. Remove from heat and let cool completely, then slice into thin strips.
02 - Julienne the carrot and cucumber into thin matchsticks. Slice the red bell pepper into thin strips. Arrange all vegetables, lettuce, mint, and cilantro on a platter. Fill a large shallow dish with warm water for softening the rice paper wrappers.
03 - Dip one rice paper wrapper into the warm water for approximately 10 seconds until just pliable and softened. Remove carefully and lay flat on a clean, damp kitchen towel or cutting board. Work quickly to prevent drying out.
04 - Arrange a small portion of lettuce, sliced chicken, carrots, cucumber, bell pepper, bean sprouts, mint, and cilantro in the lower third of the wrapper. Fold the bottom edge tightly over the filling, fold in both sides toward the center, then roll forward into a tight cylinder. Place seam-side down on a serving platter. Repeat with remaining wrappers and filling.
05 - Whisk together soy sauce, rice vinegar, sesame oil, honey, grated ginger, minced garlic, and chili flakes in a small bowl until honey is fully dissolved and ingredients are well combined.
06 - Serve spring rolls immediately, either whole or sliced diagonally in half. Arrange on a platter with the dipping sauce in a small bowl on the side for dipping.
