Cook the noodles according to the packet instructions. This will usually take 4 minutes in a pan of boiling water. Drain.
While the noodles are cooking, spray a frying pan with low calorie cooking spray. Add the chicken and brown on all sides. This should take around 4 minutes.
Add the garlic, ginger and broccoli to the pan and stir fry for 1 minute. Add the chilli, carrot and courgette and stir fry for 2 minutes.
Pour in the sauce and, when hot, add the noodles to the pan. Mix well.
Divide between two plates and serve.
