Whole Roasted Cauliflower with Lemon and Garlic is easy to prepare and is so buttery and delicious. A whole roasted cauliflower head can be the star of the show or a healthy side.

I’m not sure about that logic, but it is certainly delicious! Even Michael took a bite and said, “Oh, this is really good!” He doesn’t even like cauliflower.
