Prepare the Sauce: In a small bowl, whisk together all the ingredients for the Bang Bang sauce (mayonnaise, sweet chili sauce, Sriracha, honey, rice vinegar, and minced garlic). Set aside.
Cook the Chicken: Pat the chicken pieces dry with a paper towel. Season with salt and pepper. Dredge each piece first in cornstarch, then dip into the beaten egg.
Pan-Fry: Heat oil in a large skillet over medium-high heat. Cook the chicken in batches for 3-4 minutes per side, until golden brown and cooked through. Avoid overcrowding the pan. Place cooked chicken on a wire rack to stay crisp.
Coat Chicken: Once all chicken is cooked, place it in a large bowl. Pour about half of the Bang Bang sauce over the hot chicken and toss gently to coat.
Assemble Bowls: Divide the cooked rice among four bowls. Top with the crispy Bang Bang chicken, shredded red cabbage, julienned cucumber, julienned carrots, and sliced avocado.
Garnish and Serve: Drizzle with the remaining Bang Bang sauce. Garnish with sliced green onions, sesame seeds, and fresh cilantro. Serve immediately.
