Teriyaki Beef and Broccoli is a delicious and easy-to-make stir-fry dish that combines tender beef, crisp broccoli, and a flavorful homemade teriyaki sauce. The beef is marinated in a mixture of soy sauce, ginger, garlic, and brown sugar, then stir-fried until perfectly cooked. The broccoli is added to the pan and cooked until tender-crisp. The homemade teriyaki sauce is poured over the beef and broccoli, creating a sticky and savory glaze. Serve this dish over steamed rice for a satisfying and flavorful meal.
