There's nothing quite like a little freshly grated Parmesan cheese to wake up the taste buds and liven up a familiar side dish, like roasted vegetables. To save time, purchase precut cauliflower florets in the pre-packaged salad section of the supermarket.
Preheat the oven to 450 degrees.
In a large bowl, combine the cauliflower, oil, salt, and pepper and toss to combine. Transfer the cauliflower to a large baking sheet and spread into a single layer.
Roast until the cauliflower is golden brown, tossing occasionally, about 15 minutes. Remove from the oven, place in a serving bowl, and top with cheese. Toss to combine and serve.
