How to make it
Marinate the beef with Lee Kum Kee Premium Oyster Sauce and set aside.
Blanch the broccoli and carrots for 2 minutes then drain.
Stir-fry beef in cooking oil on medium high heat for 1-2 minutes.
Add vegetables and the rest of the sauce to cook for a further 2 minutes or until cooked (If needed, add a few tablespoon of water to have more gravy).
