Cut the pork and beef into thin strips, mix them in a bowl with 1 tbsp sesame oil and 2 tbsp soy sauce. Cover and leave to marinate for at least an hour.
In a big pot of salt water cook your noddles according to package.
While the noodles are cooking, heat one tbsp of sesame oil in your wok and fry your meat until it starts to brown (I always fry it in two batches, so the temperature doesn't drop too far in the pan). Take it out and set aside.
If necessary add another small spalsh of oil and add the onions, ginger, garlic and chili flakes and fry for one minute, stirring constantly.
Add the broccoli and stir-fry for 2 minutes. If you like your broccoli on the softer side, you can blanch it before you add it to the wok.
Add the chinese cabage and fry for 1 minute.
Add the beef, pork (don't forget the meat juices on the plate!) and the noodles. Add soy sauce to taste and mix well. Yum!
