Asian sauces for topping bowls: soy sauce, sriracha, sweet chile sauce
Heat an outdoor grill or grill pan. Season the chicken generously with salt, pepper, and garlic powder. Grill the chicken until cooked through and the juices run clear. Allow the chicken to rest until cool enough to handle. Chop the chicken into bite-sized pieces.
Assemble all the Asian Bowl ingredients: chicken, noodles, cabbage, carrots, water chestnuts, bell pepper, cucumber, scallions, cilantro, and sauces. Allow diners to assemble their own bowls.
Leftovers should be good in the refrigerator, covered, for up to 4 days.
