Cook noodles al dente (do not overcook - mushy noodles won't work). Strain and rinse under cold water until cooled. Mix or wisk together all "dressing" ingredients (peanut butter through garlic power)until blended. In large bowl stir together noodles, 2/3 sauce (reserve 1/3 for later), and vegetables (reserve 1/2 chopped greens from green onion). Chill minimum 2 hours. Transfer to a bowl or platter, if you you want. Before serving pour reserved "dressing" over noodles. Sprinkle sesame seeds and reserved green onions (and cilantro if used).
