Pat the steak dry with paper towels and slice into thin strips.
In a small bowl whisk the coconut aminos, minced garlic and arrowroot powder and set aside.
In another bowl, place the glass noodles and carefully pour boing water to cover them and let sit for 10 minutes. Then drain the noodles.
Heat the sesame oil in a large pan on medium high and cook the steak strips for 2 minutes each side. Move to a plate.
Lower the heat to medium and add the broccoli, carrots and onions stirring occasionally for five minutes.
Add the coconut aminos mixture, stirring well and allow sauce to thicken.
Add the glass noodles, steak slices, water chestnuts, rice vinegar, salt and pepper to the pan, stirring to coat with the sauce.
Simmer five minutes.
Enjoy!
