Soak the noodles in hot water following the packet instructions. While soaking, keep tossing them to avoid sticking. Drain, rinse with cold water and drain again. Leave aside.
Heat some vegetable oil in a pan. Finely chop the chillis (better to use gloves) and prepare the garlic and ginger paste by pressing or finely chopping them.
Add the chillies, garlic and ginger paste. Bring the oil to one side of the pan slightly lifting it with your hand.
Add the spice mix: five-spice powder, white pepper and chili flakes. Cook til fragrant.
Roughly chop the cabbage and zucchini and add it to the wok. While stirring keep cooking for 5-7 minutes.
Add the soy sauce, sesame oil, sriracha, brown sugar and the noodles, stir one last time and you stir fry will be ready to serve.
For presentation, add some sesame seeds on the top, finely chopped spring onion and for extra spice, chilli flakes.
