In a small bowl, combine the light soy sauce, dark soy sauce, oyster sauce, white pepper, and unsalted chicken broth (or water). Mix well and set aside.
Heat 2 tablespoons of oil in a skillet over medium-high heat.
Add the mushrooms and saute until they have released their excess liquid and are turning golden brown, about 5-7 minutes.
Add the minced garlic and cook for about 30 seconds, stirring frequently to prevent the garlic from burning.
Add KA-ME Udon Stir-Fry Noodles and pour in the stir-fry sauce.
Cook and simmer the noodles, gently separating them until they begin to loosen and absorb the sauce, about 3-4 minutes.
Toss everything together to ensure the noodles are well coated with the sauce.
Drizzle chili oil and garnish with scallions.
