Mix all the sauce ingredients in a small bowl or a jar.
Wash and chop the veggies into strips and similar size pieces.
In a large pan or wok, heat 2 tablespoons of sesame oil over high heat. Add the minced garlic cloves and sliced green onions and cook for 30 seconds. Then add the chopped vegetables, and cook for 5 minutes, stirring frequently, until the veggies are softened. If needed, add a splash of water or vegetable broth to avoid burning.
While the veggies are cooking, soak the noodles in hot water, following the packet directions, then drain.
Add the cooked noodles and the sauce to the pan. Toss well for a couple of minutes. If you like your noodles darker or more seasoned, add extra soy sauce.
Sprinkle the noodles with sesame seeds and green onion and serve.
