Soak the dried rice vermicelli in a large mixing bowl with some hot water while prepping for other ingredients.
Mix the sauce together and set aside.
On medium-high heat, add oil to the wok. Cook the prawns for about 2 minutes each side then set aside.
Drain the rice vermicelli. Cut it for convenience, or keep the noodles whole for long life. Your choice.
On medium-high heat, cook the garlic and ginger until fragrant, then add all the vegetables. Cook for 3-4 minutes until softened. Set aside.
On high heat, add a little oil to the wok and cook the rice vermicelli until it turns soft, about 3 minutes, then add the vegetable, shrimp, char siu, and eggs. Stir in the sauce. Stir fry for a few minutes until the sauce has coloured all of the noodles. Cover if necessary.
Serve immediately.
