Place sauce ingredients in a food processor. Process until smooth.
Mix noodles, carrots, and napa cabbage in a large bowl. Add enough sauce to coat the noodle mixture. (May need to add water to thin the sauce.) Sprinkle with green onions, peanuts, and sesame seeds.
Kay's tip: Use extra sauce with chicken satay, roasted pork, or pasta salad with bean sprouts, diced red pepper, sugar snap peas, grated carrot, sliced green onion, and shredded chicken.
