Stir fried beef with oyster sauce

Last night I tried out a recipe for beef with oyster sauce that I got from Kylie Kwong's Simple Chinese Cooking, which you can find here.

I didn't use as much beef, and added in mushrooms and broccoli instead of the green onion. I also used a bit more oyster sauce and thickened the sauce with about half a cup of water and some corn starch. The stir fry turned out mighty tasty, served on top of some jasmine rice.
