Preheat the oven to 400 degrees. In a large bowl, toss cauliflower with olive oil, brown sugar, Morocco spice and salt until well coated. Spread cauliflower in a single layer on a parchment-lined baking sheet and bake for 15-20 minutes, tossing once halfway through. Increase the oven to 500 degrees and continue cooking for about 10 more minutes, stirring every 5 minutes to avoid burning. When the cauliflower is well-colored and tender, remove from the oven. Let cool slightly, then toss with herbs, pomegranate seeds and a drizzle of olive oil. Season to taste with salt.
