Cook noodles according to package directions, then drain and rinse lightly with warm water. Set aside.
In a bowl, whisk together peanut butter, soy sauce, honey, vinegar or lime juice, sesame oil, garlic, ginger, and crushed red pepper flakes.
Slowly add warm water to the sauce mixture until it becomes smooth and pourable.
In a large bowl or skillet, combine the noodles, shredded chicken, carrots, bell peppers, cabbage, and green onions.
Pour the peanut sauce over the noodle mixture and toss well until everything is evenly coated.
Warm gently over low heat if serving hot, or serve chilled as a noodle salad.
Top with chopped peanuts, sesame seeds, and fresh cilantro before serving.
