Beef with Broccoli

I know that this is not a Korean dish, but Munchkin loves beef and he loves broccoli. So obviously, this is one of his favorite dishes.Get about 1/2 to 1 LB of beef. Use either flap meat or some other thinly sliced beef. Cut it up into smaller pieces. Make sure to cut against the grain. Then marinade it with: 1 TB rice wine, 1/2 TB sugar, 1/2 TB soy sauce, 1 TB water, and 1 TB corn starch.
