1 large head of broccoli or small bag of pre-cut florets.
2 garlic cloves, minced
1/2 cup chicken broth or water
2 Tablespoons oyster sauce
1/2 teaspoon red pepper flakes
2-3 Tablespoons canola oil or grapeseed oil
Slice the beef very thinly across the grain. It helps to pop it in the freezer for about 10 minutes before cutting. Place the sliced beef in a zip lock bag. To the bag add, 1 Tablespoon soy sauce, 1 Tablespoon Sherry, 1 teaspoon cornstarch. Let the meat marinate for at least 30 minutes or over night if you think about it.
In a small bowl combine, oyster sauce, 1/2 Tablespoon Sherry, 1/2 cup chicken broth or water, 2 Tablespoons soy sauce and 1 teaspoon cornstarch. Set mixture aside.
In a large skillet or wok, heat oil over high heat. Add broccoli and cook for 2-3 minutes, or until tender, but not mushy. Remove broccoli to a plate.
Add the beef to the skillet in small batches. You want the beef to sear not steam. Cook for about 3-4 minutes. Remove cooked beef to plate with broccoli.
Once all the beef is cooked add it back to the skillet along with the broccoli. Add the garlic, red pepper flakes and sauce mixture. Stir until the sauce thickens a bit.
