All of the above, plus asparagus, zucchini, eggplant, parsnips ... if it's in the grocery, I've tried roasting it. I've yet to come across a veg I don't like roasted, actually. Our go-to dinner around here is whatever is in the vegetable crisper, sprayed with a bit of olive oil, with a generous helping of black pepper, roasted.
Wow. Cauliflower roasted. How long? It doesn't burn?
Oh my goodness yes, it's the only way I'll eat it. Cut into flowerets, spread in a roasting pan, pour in a quarter cup of water or lemon juice, season any way you like and then roast for 15 minutes at 375. It's still a little firm but I like it that way. If you want it a bit mushier blanch it first and then stick it in the oven.
