This harissa roasted cauliflower is lovely when served as a sliced, main dish. You can also serve it as a mezze alongside meat or fish main courses.
Heat oven to 400 °F.
Remove the external leaves and trim the cauliflower stem. Fit a bake sheet with parchment paper. Place the cauliflower on the sheet and set aside.
Grind the spices. Finely chop the garlic and place in a bowl with the ground spices and remaining ingredients. Mix well.
Pour the marinade on the cauliflower. Spread the marinade evenly using your fingers. Cook in the oven for 30 to 40 minutes. Verify using the tip of a knife, cook longer if necessary.
Serve warm. Sprinkle on olive oil and garnish with lemon wedges.
