Beef and broccoli is a classic Chinese dish that is quick and easy to make at home. Marinate thinly sliced beef in a mixture of soy sauce, garlic, and ginger. Stir-fry the beef in a hot skillet until browned, then remove from the pan. In the same pan, cook broccoli florets until tender-crisp. Return the beef to the pan and stir in a sauce made from soy sauce, oyster sauce, and cornstarch. Serve over rice for a delicious meal.
