Cook noodles according to package instructions. Rinse with cold water and drain off excess. Put cooked noodles in a large bowl. Douse generously with soy sauce or tamari. Sprinkle with garlic and ginger powder. Add sesame oil, to taste - a little goes a long way. Toss to coat and mix-in ingredients. Sprinkle sesame seeds and toss again to coat. Add optional vegetable oil for a richer flavor, honey for a sweeter flavor and/or a bit of citrus for a more fresh flavor: fresh lemon, lime and/or orange. After tossing sprinkle with more sesame seeds and/or scallions & serve.
