Prepare noodles according to package directions. Drain and cool. Combine noodles, chicken, and next 4 ingredients (through water chestnuts) in a large bowl; toss well.
Combine chili sauce and next 5 ingredients (through ginger) in a small bowl, stirring with a whisk. Drizzle chili sauce mixture over noodle mixture; toss gently to coat. Sprinkle with peanuts. Serve immediately.
My husband and I really liked this for a simple, work night dinner. I'm not a huge fan of water chestnuts so next time I will sub bean sprouts. This dish would also be great with shrimp instead of chicken. We had some pan fried mini wontons on the side. Will definitely make again.
