Green Cauliflower with Red Onions, Feta & Pine Nuts

I love cauliflower and couldn't resist buying this green cauliflower (a cross with broccoli, but very much tastes like cauliflower). A simple treatment appealed, so I roasted the cauliflower in a 425 F degree oven with a tiny amount of olive oil, red onions, garlic, and a little fresh thyme.  Added pine nuts and feta cheese for the last 5 minutes and this is a deliciously light one dish wonder!
