Place the noodles in a bowl, and cover them in boiling water. Cover with cling film then microwave for 60 to 90 seconds.
Spray a frying pan or wok with low calorie cooking spray, then cook the garlic, ginger and onions until they start to brown.
Remove the cooked salmon from the bag and place on top of the noodles. Cut open the sauce sachet and drizzle over the fish.
Serve.
