Beef and broccoli is a classic Chinese dish that is quick and easy to make. Marinate thinly sliced beef in a mixture of soy sauce, garlic, ginger, and cornstarch. In a hot skillet or wok, stir-fry the beef until browned. Remove the beef from the pan and stir-fry broccoli florets until tender-crisp. Return the beef to the pan and add a sauce made from soy sauce, oyster sauce, and a touch of sugar. Serve over steamed rice for a flavorful and satisfying meal.
