Prepare dry rice noodles as per packet directions.
Heat oil in a wok over medium-high heat, add garlic and red chilies, stir-fry until aromatic or 10–20 seconds.
Add the chicken pieces and stir-fry until they’re nearly done.
Add sauces and seasonings: sugar, soy sauce, fish sauce, flavor seasoning, and oyster sauce. Make sure each piece of chicken is coated with sauce.
Add the carrots, baby corns, finger roots, and fresh peppercorns, cooking for about 10–20 seconds.
Toss in the rice noodles and ensure they are well coated with sauce and softened to your liking. (I like mine a bit chewy.)
Remove from heat and stir in holy basil. Serve hot!
