Bring a pot of water to a boil and add the noodles. Allow them to cook for about 6 minutes or until they reach your desired doneness. Drain and set aside.
Add all the ingredients for the spicy beef to a bowl, rub thoroughly then allow it to marinate for 20 minutes at room temperature.
Set a nonstick skillet on medium high heat and once hot, add the beef. Let the beef cook without stirring for 2 – 3 minutes to sear the meat and add color to it. Then toss the meat in the skillet and add the veggies and toss. Then the noodles and gently toss everything together for an additional 4 – 6 minutes.
Pour in the dark soy for the final flavor and to add color to it, and season to taste with tamari.
Garnish and enjoy!
