Pad thai with prawns or chicken

Pad thai is delicious, and I'm always wanting this from the local Thai restaurant. However it's absolutely packed with calories, so this is the way to make it yourself for a reasonable amount of calories. 
Serves two, 340 calories per serve. Add more veges and cut out the noodles to reduce calories.

Ingredients:
150g chicken, diced or 250g raw prawns, peeled and deveined
75g rice vermicelli noodles
1 onion, diced
1 red capsicum, sliced
1 cup mushrooms, sliced
1 carrot, thinly sliced
Handful snow peas, cut in half
Sauce: (combine in a cup to add all at once)
1 tsbpn hoisin
1 tbspn fish sauce
1 tbspn oyster sauce
2 tbspn brown sugar
1 tspn chilli (more or less depending on how much you can handle)
1 tbspn lime juice, or juice and zest of 1 lime

Method: 
In a wok or large frypan, spray oil to cook the chicken or prawns, then remove them to put in a bowl.
Cook the noodles according to packet instructions.
In the same pan, fry up the onion and garlic for 3 minutes.
Add the carrots and cook for 2 minutes, then the rest of the veges, cook for another minute or two.
Add the sauce and the chicken/prawns . Cook for a few minutes until the sauce thickens and reduces slightly.
Add noodles, toss through to heat and serve.
