In 2-quart saucepan, heat 1 1/2 cups water to boiling over high heat. Break apart noodles before opening soup packages. Stir 2 of the seasoning packets and all of the noodles into boiling water. Cook 2 to 3 minutes, stirring constantly, until noodles are tender; do not drain.
In large bowl, toss noodles, cabbage, chicken, carrots and onion. In small bowl, stir together dressing, sugar and remaining seasoning packet. Toss dressing with salad.
Cover and refrigerate up to 1 hour. Stir in wasabi peas and sesame seed just before serving.
