How to Make Black Pepper Beef Stir-Fry with Rainbow Peppers and Sesame Finish
Step 1: Prepare the Beef Marinade
In a bowl, combine the soy sauce, oyster sauce, hoisin sauce, freshly ground black pepper, and cornstarch. Mix well to create a marinade. Add the thinly sliced beef to the marinade. Allow it to marinate for at least 15 minutes.

Add the marinated beef to the hot wok in a single layer. Let it sear without moving it for about 2 minutes until caramelized. Then stir-fry for an additional 2–3 minutes until cooked through.
Step 4: Stir-Fry the Vegetables
Remove the beef from the wok and set aside. In the same wok, add more oil if necessary. Toss in the sliced onions and bell peppers. Stir-fry for about 3–5 minutes until they are tender-crisp.
