For a sweeter tahini drizzle, add another teaspoon of honey. Maple syrup can also replace honey if you prefer a different sweetener.
If you enjoy spicy harissa cauliflower, use a hotter harissa paste or add a small pinch of crushed red pepper.
Serve this dish with couscous, quinoa, rice, warm flatbread, lentils, or a fresh cucumber and tomato salad. It can also be added to grain bowls with chickpeas for a more substantial meal.
