Follow the instructions on the package for your noodles. (The one I used said to soak it in hot tap water for a minute, then drain.) Make sure to drain the noodles well, then set it aside.
In a small bowl, mix the water, shoyu, vegetarian stir-fry sauce and white pepper. Set it aside.
Heat the sesame oil in large wok or pan over medium-high heat. Add the vegetables and stir-fry for 3-5 minutes, until they soften.
Add the sauce mixture and quickly toss the vegetables in it.
Add the noodles and toss them until they are evenly coated in the sauce. Stir-fry until the noodles are completely heated through (about 3-5 minutes). If the noodles seem dry, add a little more water, up to 1/4 cup. Keep in mind that the noodles should be moist, but not “saucy.”
Garnish with green onions, and serve. Enjoy!
