In a medium bowl, combine the cauliflower, cheese, parsley, garlic powder and pepper. Season to taste with salt. Toss to mix. Drizzle on the oil and toss again. Transfer the mixture to a small nonstick baking dish and place in oven. Bake for 15 to 17 minutes, tossing once, or until lightly browned and crisp-tender. Serve immediately.
