Boil a pot of water and cook noodles according to package directions until they're just tender.
Meanwhile, add the sauce ingredients to a small bowl, and then prep the garnish ingredients and set aside.
Add the oil and chicken to a skillet or wok. Cook on medium-high heat for 5 minutes, stirring often.
Add the sauce to the pan and give it a good stir to coat the chicken. Cook for an additional couple minutes, stirring often, or until the chicken is cooked through (but don't overcook). The sauce will thicken up.
Once the noodles are done, drain them and add to the pan. Toss with the chicken (I use tongs). You can either add the garnish ingredients right to the pan or to each bowl when you plate it.
Eat it immediately or enjoy cold as a noodle salad.
