Beef and Broccoli

We had some ymuuy heads of broccoli sitting in our fridge just waiting to be used.  I wanted to something different than just steaming and eating them though, my husband suggested beef and broccoli.  After looking through a lot of recipes online, I found this one and it was great!  We loved the flavors!  I used about a pound of meat and doubled the marinade and the sauce and I thought that was perfect.
