Heat 2 tbsp of oil in a wok on medium heat.
Fry off prawns briefly on each side, then add chicken and onion. Stirring constantly, until just cooked, this should take approximately 3 minutes.
Add spice and sugar mix and stir through. Cook for 1 minute.
Add noodles and wet ingredients. Toss through and stir constantly for 1 minute.
Push everything to one side of the wok. Add the remaining oil to the wok. Pour in eggs to cover as much of the wok as possible. Push the noodles onto the eggs and leave to cook under the noodles for 1 minute.
Begin moving your ingredients in the wok, ensuring the eggs have been tossed through the noodles. Add vegetables and toss through noodles until combined, for approximately 1 minute.
