Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

Cut the cauliflower into bite-sized florets and place them in a large bowl.

In a separate bowl, whisk together olive oil, chili powder, garlic powder, salt, pepper, and lime juice.

Pour the mixture over the cauliflower florets and toss until evenly coated.

Spread the florets on the baking sheet in a single layer and roast for 25-30 minutes until golden brown and tender, shaking the pan halfway through for even cooking.

Allow to cool slightly before serving. Drizzle with additional lime juice if desired.
