Bring salted water to a boil in a large stockpot.  Once at a rolling boil, add the soba and cook according to package directions (5 minutes). 

Immediately drain and plunge into a bowl of ice water.  Once cooled, drain and drizzle with 3 tablespoons sesame oil then set them aside. 

Once done, drain the soba noodles and rinse them thoroughly in a bowl of iced water. Drain the noodles again, making sure to remove any excess water. Then, drizzle dark sesame oil over the noodles and stir to evenly coat them. Set aside.

In a small bowl, whisk together the peanut butter, fresh ginger, fresh garlic, chili sauce, dark soy sauce, water, and lime juice.  Whisk until combined. 

In a large bowl, combine the noodles, sliced vegetables, herbs, and salad dressing.  Toss to combine and coat all pasta well.  If desired, add sesame seeds at this time or save to garnish. 

Serve with additional fresh cilantro, lime wedges, or sesame seeds.
