01 - Soak the bihon noodles in warm water for 10 minutes until softened, then drain thoroughly and set aside.
02 - Heat 2 tablespoons of oil in a large wok or skillet over medium-high heat. Sauté garlic and onion until fragrant and translucent, approximately 2 minutes.
03 - Add chicken slices and cook until lightly browned and cooked through. Add shrimp and stir-fry until pink, about 2 minutes. Remove proteins from the pan and set aside.
04 - In the same pan, add carrots, cabbage, and snow peas. Stir-fry for 2–3 minutes until just tender-crisp.
05 - Return the cooked chicken and shrimp to the pan. Pour in soy sauce, oyster sauce, fish sauce, and chicken broth. Bring to a gentle simmer.
06 - Add the drained bihon noodles, tossing gently with tongs to combine and absorb the sauce. Cook for 3–4 minutes until noodles are heated through and have absorbed the flavors.
07 - Season with black pepper and adjust salt or sauces to taste if needed. Transfer to a serving platter, garnish with chopped scallions, and serve with lemon or calamansi wedges on the side.
