Cauliflower is a great substitute for white noodles and white rice, because of its color, versatile texture, and because cauliflower is a member of that ultra-healthy family of cruciferous veggies. People who consume the most of these types of vegetables (cauliflower, broccoli, cabbage, Brussels sprouts, bok choy, and kale) have lower rates of several kinds of cancer, and laboratory tests have shown that certain compounds in cruciferous vegetables actually stop the growth of many types of cancer cells.
One way to use cauliflower is to steam or boil it, chop it roughly, and then substitute it for half the macaroni in your favorite mac and cheese recipe. Another option is to make a roasted cauliflower casserole, leaving out the pasta altogether. Chop cauliflower into chunks, and arrange in a baking dish. Add two to three cloves of garlic, minced. Drizzle with olive oil and squeeze a lemon over the pieces. Season with salt and pepper. Bake in a 400-degree F oven for 20 minutes or until the tops are browned. Remove and sprinkle generously with grated Parmesan.
