A beef stir-fry is a versatile and healthy dish that can be customized to your taste. Start by marinating thinly sliced beef in a mixture of soy sauce, ginger, garlic, and a touch of honey. Heat oil in a wok or skillet and stir-fry the beef until browned. Remove the beef from the pan and stir-fry your choice of vegetables like bell peppers, broccoli, and carrots. Add the beef back to the pan, along with the sauce made from soy sauce, oyster sauce, and cornstarch. Serve over rice or noodles for a satisfying meal.
