Gently wash produce under cool running water, pat dry, and prepare as directed.
Preheat the oven to 400°F.
Place the cauliflower on parchment paper on a rimmed baking sheet. Drizzle with the olive oil and sprinkle with salt. Use clean hands to distribute the oil evenly.
Roast 20-30 minutes, or until browned at the edges.
Remove the tray from the oven.
In a small bowl, combine the breadcrumbs and cheese. Sprinkle evenly over the cauliflower.
Return to the oven and roast until the cheese melts, 5-10 minutes.
Serve immediately.
