Stir Fry Beef with Broccoli

My attempts at stir fry beef have always turned out tough and chewy - probably due to cut of steak and method of cooking. This time I found flank steak and followed a recipe using a marinade, high heat quick cooking. I only had half the steak needed so sauce was a bit much. Recipe adjusted for this below.

• 2/3 lb flank steak
• 1/4 c oyster sauce
• 2 T sesame oil
• 1/3 c sherry (or half water/half apple cider vinegar)
• 1 t soy
• 1 t brown sugar
• 1 t cornstarch
• 3 T oil
• 3 thin slices ginger
• 1 cl garlic, smashed
• 1 lb broccoli - florets and small stem pieces

1. Combine the oyster sauce to cornstarch.
2. Thinly slice the steak, against the grain.
3. Marinate the meat in the sauce for at least 30 min in the fridge.
4. Heat the oil in a wok and add the ginger and garlic. Saute until aromatic and then discard the ginger and garlic. Add the broccoli to the fragrant oil and cook for 5-7 minutes.
5. Remove the broccoli and then fry the beef in small batches, about 5 min each.
6. Once done, add the broccoli back and cook for 3 min.
7. Serve over rice or hefen noodles.
