Boil noodles for about 5 minutes or according to packaging instructions. Drain into a colander. Mix in a teaspoon of canola oil to prevent noodles from sticking.
Combine chicken and marinade ingredients in a bowl and allow it to sit for 10 minutes. Combine dark soy sauce and fish sauce in a separate bowl.
Heat oil in a wok or large fry pan. Stir in garlic for about a minute. Add chicken and let it cook for 3 minutes. Add crab sticks and carrots and continue to stir for another 2 minutes.
Now, add the noodles followed by the sauce. Stir to get noodles and ingredients well coated. This should take 2 to 3 minutes.
Finally add bean sprouts and green onions. Continue to stir for another minute. Do not overcook bean sprouts. They should remain crunchy.
