I tried roasting the cauliflower a few weeks ago. I just used the olive oil, Kosher salt, pepper, and crushed garlic. My husband and son wanted grated jack/cheddar on their servings. It was ALL delicious and it was gone so fast. None of us were cauliflower fans. In fact, I verged on the border of hating cauliflower. Now, I am buying it at least once a week. I have been raving about it to all of my family and friends. Many have said they don't like cauliflower either. I know there will be many more converts out there!
I'm looking forward to trying the balsamic/parmesan and many other combinations.
