# How-to Steps:
01 - In a bowl, toss the sliced beef with 1 tablespoon soy sauce and 1 tablespoon cornstarch. Set aside to marinate for 10 minutes.
02 - In a small bowl, whisk together all sauce ingredients: soy sauce, oyster sauce, water, brown sugar, cornstarch, and sesame oil. Set aside.
03 - Heat 1 tablespoon vegetable oil in a large skillet or wok over high heat. Add the broccoli and stir-fry for 2–3 minutes until bright green and just tender. Remove and set aside.
04 - Add the remaining tablespoon of oil to the pan. Add the marinated beef in a single layer and sauté undisturbed for 1 minute, then stir-fry for 2–3 minutes until browned and nearly cooked through.
05 - Add garlic and ginger, stir-frying for 30 seconds until fragrant.
06 - Return the broccoli to the pan. Pour in the prepared sauce and stir to coat all ingredients. Cook for 1–2 minutes until the sauce thickens and everything is heated through.
07 - Serve immediately over steamed rice. Garnish with sesame seeds and spring onions if desired.
