INGREDIENTS:
1/2 cup oyster sauce
1/4 cup chicken broth
2 tablespoons brown sugar
2 teaspoons sesame oil
2 teaspoons cornstarch
1 pound flank steak, trimmed and sliced thin (The nice butcher at the grocery store cut mine for no additional charge.)
2 tablespoons vegetable oil (I used PAM instead)
1 1/2 pounds broccoli, chopped (I used one bag of frozen broccoli florets)
1 red pepper, stemmed, seeded and chopped medium
1/3 cup water
6 garlic cloves, minced
1 tablespoon grated ginger

DIRECTIONS
Whisk the oyster sauce, broth, brown sugar sesame oil and cornstarch together. Pat the the beef dry with paper towels, then season with salt and pepper. Heat 1 tablespoon of the oil in a 12-inch skillet over high heat until just smoking. Brown the beef lightly, about 3 minutes, then transfer to a clean bowl. Add the broccoli, bell pepper and water to the skillet and return to medium heat. Cover and cook until the broccoli is bright green, about 2 minutes. Uncover and continue to cook until the liquid evaporates, about 3 minutes. Add the remaining 1 tablespoon oil (I skipped this step), the garlic, scallions and ginger and cook until fragrant, about 30 seconds. Briefly re-whisk the oyster sauce mixture to recombine, then add to the skillet with the beef. Toss until all the ingredients are well coated with sauce.
