01 - Season the chicken breast with salt and pepper. Heat sesame oil in a skillet over medium heat. Cook the chicken for 4–5 minutes per side, until cooked through. Let cool, then slice thinly.
02 - Julienne the carrot and cucumber. Slice the red bell pepper into thin strips. Prepare lettuce, mint, and cilantro. Fill a large shallow dish with warm water for softening rice paper.
03 - Dip one rice paper wrapper into the warm water for about 10 seconds until just softened. Lay it flat on a clean, damp kitchen towel or cutting board.
04 - Arrange a small amount of lettuce, chicken slices, carrots, cucumber, bell pepper, bean sprouts, mint, and cilantro in the lower third of the wrapper. Fold the bottom edge over the filling, then fold in the sides and roll tightly into a cylinder. Repeat with remaining ingredients.
05 - Whisk together soy sauce, rice vinegar, sesame oil, honey, ginger, garlic, and chili flakes in a small bowl until well combined.
06 - Serve the spring rolls whole or sliced in half, with the dipping sauce on the side.
