A homemade beef stir-fry is a quick and healthy dinner option. Thinly sliced beef is marinated in a mixture of soy sauce, ginger, garlic, and sesame oil, then stir-fried with colorful vegetables like bell peppers, broccoli, and carrots. The result is a flavorful and nutritious dish that can be served over steamed rice or noodles. Customize the stir-fry with your favorite vegetables and sauces.
