MARINADE:

Whisk together the baking soda, sugar, cornstarch, soy sauce, water, and vegetable oil in a large bowl. Toss in the thin sliced steak and coat with the marinade. Cover and refrigerate for at least a hour.

In a small bowl stir together the soy sauce, brown sugar, garlic, flour, and sherry until smooth then set aside.

In a large pan heat 2 tablespoons of vegetable oil over high until shimmering. Add broccoli and saute for 3 minutes, stirring often. Transfer the broccoli over to a plate.

Carefully add the remaining tablespoon of vegetable oil to the hot pan. Add the marinated meat and half of the marinade's mixture to the pan. Saute for 3-4 minutes stirring often until the meat is done and no longer pink.

Stir back in the broccoli and the rest of the marinade mix and saute for one minute.

Serve over cooked rice.
