In a medium mixing bowl, take steak slices and thoroughly coat with starch. Set aside and let the meat rest for 10 minutes
Over med-low heat, warm a small saucepot with the 2 tsp of vegetable oil
Add the ginger and garlic, quickly stir and add the soy sauce and water
Bring to a low boil; add the sugar and stir until fully dissolved. Remove from heat and set aside
In a large skillet or deep-sided frying pan, warm the 1 cup of cooking oil over medium heat
Add the meat and sautee for approx 2 minutes, until just browned (Do not overcook).
Use a slotted spoon to transfer browned meat into a bowl.
Cook in batches so that the pan does not get overcrowded.
Once all the meat is browned and set aside, drain the pan of the excess oil
Return pan to heat, and dump all the meat into the pan, sauteeing for about one minute
Add the sauce and cook for an additional minute, while stirring to coat the meat and scraping the pan to get any bits incorporated into the sauce
Add the scallions and cook for one additional minute
