Step 1

Cut flank steak into thin slices about ½ centimeter in thickness. Make sure you are cutting against the grain.

Step 2

Marinate in soy sauce, corn starch, sugar, baking soda, and oil for at least 30 minutes.

Step 3

While the beef is marinating, soak your noodles in boiling water for 10-15 minutes. We want them to be about 75% cooked through because they will continue cooking in the wok later.

Step 4

Heat up a wok with oil over high heat and begin to cook beef about 80% through then set aside.

Step 5

Add more oil into the wok then add onions, and beansprouts (washed beansprouts) Cook for 1-2 minutes.

Step 6

Add drained vermicelli noodles.

Step 7

Add soy sauce, dark soy sauce, and oyster sauce along with beef and green onions. (green onion washed and cut into 6 inch segments)

Step 8

Once everything is mixed thoroughly, season with salt, top with sesame oil, and chili oil.
