Preheat your oven to 450°F (230°C).
Chop the cauliflower into bite-sized florets.
Spread the florets out on a baking sheet, making sure not to overcrowd them.
Drizzle with olive oil, season with salt and pepper, and toss to coat evenly.
Roast for 20–25 minutes, stirring halfway through, until golden and tender.
While the cauliflower roasts, whisk together vinegar, olive oil, fresh herbs, salt, and pepper. Optional: add a pinch of red pepper flakes for some heat.
Once the cauliflower is golden, remove from the oven and drizzle with the vinegar mixture. Enjoy while it’s warm!
