1. Add soy sauce to the meat and mix. Toss with cornstarch. Lay the steak out in a flat container or a baking pan and freeze for about 45 minutes. (This keeps the meat from sticking together .)
2. Heat oil in a large saucepan for frying. (Do not use a skillet, or it will splatter everywhere) Fry the meat in batches, about one third at a time, for two minutes. Lay out on paper towels to drain.
