For the mixed vegies, use a combination of carrots, cabbage, green beans, peas etc. Chop them into bite-size pieces. If in a hurry use frozen mixed vegetables. This calls for dark soy sauce, which is thicker and sweeter than regular, as well as regular soy sauce. If you can't find the dark, use all regular.
In a wok or a large pan over medium heat, add oil and chicken and cook until tender. Transfer to a plate and set aside.
Add garlic and onion and cook for 2 minutes. Add the cooked chicken and season with a little salt and pepper.
Stir in the veggies and cook for another 3-4 minutes or until a little tender
Add all the ingredients for the pancit sauce and bring to a boil.
Add rice noodles and stir until all the noodles are coated with the sauce. Keep on stirring and cooking until the noodles are tender (3-4 minutes). Add more stock (or water) if the dish is dry before the noodles are tender.
Season with salt and pepper and more soy sauce if necessary. Serve immediately.
