Oven Roasted Cauliflower

I found this purple and green cauliflower at the grocery store and decided it was too beautiful to pass up. I've never much liked cauliflower but I LOVE it roasted like this.

1 head purple cauliflower
1 head green cauliflower (broccoflower)
a handful of garlic cloves
4 T EVOO
kosher salt and pepper to taste
parmesan cheese (I didn't measure this- probably about 1/4 cup)

Preheat oven to 425º; cut cauliflower into florets- cut huge ones into roughly 2" pieces and place in a large bowl. Toss in garlic and EVOO; season with salt and pepper. Roast on a rimmed baking sheet for 35 minutes. Take the cauliflower out of the oven and carefully stir and turn; toss with Parmesan cheese. Return to the oven and roast another 10-15 minutes until nicely caramelized.
