Cook the beef: Add the marinated beef to the pan. Cook for about 3-4 minutes, until browned and cooked through.
Add broccoli: Toss in the broccoli florets and add a splash of water. Cover the pan and cook for another 3-5 minutes until the broccoli is tender but vibrant.
Season and serve: Taste and season with salt and pepper. Serve hot over cooked rice.
Notes
Use thinly sliced beef for tenderness and avoid overcooking the broccoli for best texture.
