Step 1
Bring a large pot of water to a boil. Add noodles, and cook until barely tender, about 5 minutes; drain in a colander, rinse with cold water, and drain again. Transfer to a bowl and add 3 tbsp. sesame oil; toss until evenly coated and set aside.
Step 2
In another bowl, whisk together remaining sesame oil, soy sauce, vinegar, sesame paste, peanut butter, sugar, chili-garlic paste, sesame seeds, garlic, scallions, and ginger. Pour over noodles along with cucumber and carrot, and toss until evenly combined. Transfer to a serving bowl, and garnish with peanuts.
