Cook the pancit canton noodles according to package instructions. Drain and set aside.
In a large skillet or wok, heat vegetable oil over medium-high heat.
Add the sliced chicken and pork. Cook until browned and cooked through, about 5-7 minutes. Remove from the pan and set aside.
In the same skillet, add a bit more oil if needed. Sauté the chopped onion and minced garlic until fragrant and softened, about 2-3 minutes.
Add the carrots, bell peppers, and cabbage. Cook until the vegetables are tender-crisp, about 3-4 minutes.
Return the cooked chicken and pork to the skillet with the vegetables.
Stir in the soy sauce, oyster sauce (if using), and chicken broth. Bring to a simmer and cook for another 2-3 minutes.
Add the cooked noodles to the skillet. Toss everything together to combine well and heat through. Adjust seasoning with salt and black pepper.
Garnish with chopped green onions.
Enjoy your meal!
