Fiery Garlic Flank Steak Stir-Fry

1.In a bowl, combine the sliced flank steak with soy sauce, oyster sauce, and cornstarch. Mix well to coat the meat evenly and let it marinate for at least 15 minutes.

2.Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Once hot, add the marinated flank steak in a single layer and sear for about 2-3 minutes until browned. Remove the steak from the skillet and set aside.

3.In the same skillet, add the remaining tablespoon of vegetable oil. Add minced garlic and ginger, then toss in the bell pepper slices. Stir-fry for about 1-2 minutes until the pepper is tender-crisp and the aromatics are fragrant.

4.Return the cooked flank steak to the skillet with the bell peppers. Add red pepper flakes, sesame oil, salt, and pepper to taste.

5.Stir everything together and cook for an additional 1-2 minutes to heat through and ensure the sauce coats the meat and peppers thoroughly.

6.Remove from heat, garnish generously with chopped green onions, and serve immediately.
