Combine the tamari, honey, mirin, vinegar, chili garlic sauce, and sesame oil in a small bowl and set aside.

Place the noodles in a bowl, add the cornstarch, and toss well to coat.

Heat the oil in a large non-stick skillet over medium-high heat. Add the noodles and cook for about 1 minute, gently tossing occasionally. Add the sauce and cook, stirring occasionally, until the noodles are tender, and the sauce has thickened, 3-4 minutes.

Garnish with green onion and sesame seeds.
