Cook the noodles in a pot of boiling salted water until just tender but still firm to the bite. Drain well. Rinse under cold water, and transfer to a bowl. Add the soy sauce and sesame oil and toss. (Can
be made up to two hours ahead. Cover, let stand at room temperature.)
Heat vegetable oil in a wok or heavy large skillet over medium heat. Add the ginger and garlic; stir-fry 30 seconds. Add the onions; stir-fry two minutes. Add the noodles. Stir-fry to heat through and serve.
