Dressing: In a bowl, whisk together all dressing ingredients until smooth. Set aside.
Cook soba noodles according to package directions. Once cooked, drain and rinse under cold water for 30 seconds. Shake off excess water and set aside.
Toss chicken, vegetables, and noodles with enough dressing to coat everything to your preference. ((You may have extra dressing. Add more as the noodles absorb it). Serve cold (chill in fridge for 15-20 minutes and toss again) or at room temperature. Top with crushed peanuts and crispy fried onions if desired.

Notes
Note 1: The best substitute for soba noodles is thin spaghetti or angel hair pasta. Use 9 ounces, not a full one pound package. The dressing is already fairly salty, so I skip salting the pasta water, but you can season the finished salad to taste if needed.Note 2: Sweeten to taste based on how much Sriracha you use. Less Sriracha usually means less honey is needed.Storage: This salad is best the same day but keeps for 1 to 3 days. For longer storage, keep the salad, dressing, and toppings separate and toss just before serving.
