In a bowl evenly sprinkle the sesame oil, pepper, ginger and salt along the cubed steak.

Pour the vegetable sauce mixture into the pan with the beef and cook for an additional 5-7 minutes until sauce has thickened and vegetables have softened.
Lower heat and add in noodles. Thoroughly sauce the noodles. Cook for another 2-3 minutes.
