Preheat the oven to 415 degrees F and line a large baking sheet with parchment paper.

Add the raw cauliflower to a large mixing bowl. Drizzle with olive oil, and sprinkle with nutritional yeast, sea salt, paprika, and cayenne pepper. Use your hands to toss and mix everything together until the cauliflower florets are well-coated.

Spread the cauliflower over the prepared baking sheet and roast on the center rack for 30 to 40 minutes, stirring half-way through, or until cauliflower is golden-brown and tender.

Remove from the oven and taste cauliflower for flavor. Sprinkle with sea salt and additional nutritional yeast if desired. Serve with chopped pistachios, pine nuts, walnuts, or pecans alongside your favorite entree.
