Heat the olive oil in a large skillet and cook the steak until it starts to brown, about 4 to 5 minutes. Add sauce and stir in with the steak, it should start to thicken immediately.
Add broccoli and cook for an additional 2 minutes until broccoli is tender and sauce is thickened.
Serve over rice or noodles.
A good substitute for the sherry would be apple cider.
