To begin, you will need 8 ounces of long noodles. You can use spaghetti noodles or head to your local Asian market and pick up some lo mein noodles. I used Philippine-style noodles. Cook them according to package directions until just done.
Thinly slice the flank steak into strips. Toss it in a bowl with the cornstarch to coat it.
In a large skillet or wok, heat the coconut oil over medium high heat. Toss in the beef and cook until just browned. Add in the fresh ginger and garlic. Stir it in.
Add in the frozen stir-fry vegetables along with the beef broth and brown sugar. Cover the wok/skillet and steam the vegetables over medium heat for about 4-5 minutes, or until they just begin to get tender.
