Beef and Broccoli Stir Fry

The first time I made this I used green beans instead of broccoli.  It tasted OK but it tastes much better with the broccoli.  The green beans did not soak up the sauce as well as the broccoli did, and I think that makes a big difference.

Ingredients:
1/3 cup chicken broth
1/4 cup oyster sauce
2 tbs soy sauce
2 tbs rice vinegar
1 tsp red pepper flakes (more for a spicier dish)
2 tbs vegetable oil
1 (1 1/2 pound) Flank steak, trimmed and sliced thin against the grain
12 oz broccoli florets
2 tbs minced garlic
1 tbs minced ginger


In a large measuring cup or bowl, whisk broth, oyster sauce, soy sauce, vinegar and pepper flakes.
In a large skillet heat 1 tablespoon of oil.  Once the oil begins to smoke add broccoli and cook, stirring occasionally.  Transfer to a large bowl once the tips of the broccoli start turning slightly brown.

Pat flank steak dry with paper towels.  Heat 2 tsp of oil in skillet and add 1/2 the flank steak.  Cook until meat is brown.  Transfer to bowl with broccoli.  Repeat with the remaining flank steak.

Now add the remaining 2 tsp of oil.  Add garlic and ginger and cook until fragrant.  Stir back in the steak and broccoli.  Whisk broth mixture to recombine and add to skillet and cook, stirring constantly until sauce is thickened.  Serve over rice.
