Tari posted this recipe awhile back. Since then I have made it a few times. I didnt add any cheese and I only had powdered garlic and it was still delicious.
Preheat oven to 450F. Cut up a head (or more) of cauliflower. Drizzle with olive oil (I used Wegman’s Basting Oil with garlic and herbs). Toss to coat. Dump onto a foil lined baking sheet. Sprinkle with fresh grated parmesan (maybe 1/4-1/2 cup). Bake at 450F for 20 minutes or so.
