Mix together the marinade ingredients.
Add in the beef, making sure that all of the pieces are coated. Give the beef a little massage. Let marinate for 15 minutes.
Mix together the sauce ingredients. Set aside.
Heat up 2 tbsp of cooking oil in a large sauté pan or wok over medium high heat. Add the beef in a single layer. Sauté the beef for 1 minute a side without stirring. This will allow the beef to get a nice sear. When done, remove from pan and set aside.
Reduce the heat to medium. In the same pan, add another tbsp of oil. Sauté the onions, garlic, and ginger for 2 minutes.
Add in the last tbsp of cooking oil. Stir in the rice noodles, making sure that they are coated in the garlic, onion, and ginger. Stir fry for 2-3 minutes. If the noodles begin to stick to the bottom, add a little bit of water.
Stir in the beef and the sauce. Make sure all of the noodles are coated in the sauce. Cook for a minute.
Stir in the bean sprouts and green onions.
Cook for 2 more minutes.
