Rinse cauliflower and chop into medium size pieces. Pat dry with a paper towel.
Place cauliflower on a rimmed baking sheet.
Drizzle lightly with olive oil and toss.
Combine spices in a small bowl and sprinkle over cauliflower.
Sprinkle lightly with salt and pepper and toss.
Roast for approximately 20 minutes, turning the cauliflower half way through. Keep a close eye on it after flipping to make sure it doesn't burn.
Adjust salt and pepper to taste, squeeze fresh lime juice over the top, and sprinkle with fresh chopped cilantro.
