Add steak to the pan and sear on high heat for a couple minutes until browned on both sides. Do not over crowd the pan. Cook steak in multiple batches if need be.
Remove steak from pan and combine with vegetables.
Stir Fry Sauce
Reheat wok over medium/high heat.
Add oil.
Saute garlic and shallot for a minute or two until soft and translucent but not brown.
Add oyster sauce, soy sauce, chicken stock and sesame oil.
Bring to a simmer for a couple minutes.
Add green onions.
Add vegetables and steak back to sauce and allow to heat through for a minute before serving.
Recipe Notes
***We prefer to serve the noodles separately from the stir fry. That way, each person can choose how much of each they want. Alternatively the noodles can get tossed with the sauce just prior to adding the vegetables and steak back to the sauce.
