Cook the pasta or noodles until they are al dente, strain, and set aside.
Into a wok, add 2 tablespoons of stir-fry oil or sesame oil over medium-high heat.
When the oil is hot, add marinaded chicken pieces.
Cook the chicken with a bit of salt and white pepper to taste.
When the chicken is done, remove the chicken with a slotted spoon and set it aside.
Add more oil as needed and sauté the onions, peppers, and chopped garlic for 4-5 minutes.
Add the carrots and continue for another 2-3 minutes.
Add the noodles, pour the sauce over the stir-fry, and toss to coat evenly.
Serve with green onions.
