01 - Slice cucumber, julienne carrot, shred cabbage, slice spring onions, and chop cilantro. Set aside in separate containers for assembly.
02 - Whisk together cornstarch, salt, pepper, and egg in a large bowl until smooth. Add chicken pieces and toss thoroughly to coat each piece evenly with the batter.
03 - Heat vegetable oil in a large skillet over medium-high heat. Fry chicken pieces in batches without overcrowding the pan. Cook until golden brown and crispy, approximately 3-4 minutes per side. Transfer to paper towels to drain excess oil.
04 - Combine mayonnaise, sweet chili sauce, sriracha, honey, and rice vinegar in a medium bowl. Whisk until completely smooth and well incorporated. Taste and adjust sriracha for desired heat level.
05 - Transfer crispy fried chicken to a large mixing bowl. Pour half of the bang bang sauce over the chicken and toss gently until each piece is evenly coated. Reserve remaining sauce for serving.
06 - Divide cooked jasmine rice evenly among 4 serving bowls. Arrange crispy chicken, cucumber, carrot, purple cabbage, and spring onions in sections over the rice.
07 - Drizzle reserved bang bang sauce over each bowl. Sprinkle with toasted sesame seeds and fresh cilantro. Serve immediately with lime wedges on the side for squeezing.
