This is sort of a repeat post, because I used almost the same recipe as the golden cauliflower that I made a few weeks ago. However, I adapted it a little bit to suit the purple cauliflower, so I thought I'd show what I did. Changes are in italics.
Roasted Purple Cauliflower
3 large cloves of garlic, minced
1 tablespoon olive oil
3 tablespoons of red wine
1 medium sized head of purple cauliflower, separated into florets
1/2 tsp coarse sea salt (I used red sea salt this time)
1/4 tsp pepper
2 tablespoons parmesan cheese
1. Preheat the oven to 450 degrees.
2. Place cauliflower florets in a large roasting or casserole dish. Add the garlic, olive oil, wine, salt, and pepper; toss thoroughly.
3. Bake for 25 minutes, stirring halfway through.
4. Remove from oven, top with Parmesan cheese. Stir, and serve.
