While the beef is marinating, Separate your fresh rice noodles in a bowl.
If you are using dry noodles 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.
300 g fresh rice noodle or dry
Heat up a wok with oil over high heat and begin to cook beef about 80% through then set aside.
Add more oil into the wok then add onions, and beansprouts (washed beansprouts) Cook for 1-2 minutes.
1 handful bean sprouts, ½ yellow onion
Add drained rice noodles.
Add soy sauce, dark soy sauce, and oyster sauce along with beef and green onions. (green onion washed and cut into 6 inch segments)
1½ tbsp soy sauce, 1½ tbsp oyster sauce, 1½ tbsp dark soy sauce, 1 handful green onion
Once everything is mixed thoroughly, season with sugar, top with sesame oil, and chili oil.
Notes
Stirring technique: once your put the rice noodles into the wok, switch to using chopsticks which will help prevent the noodles from breaking.
