Step 2

Preheat the oven to 425°F.

Step 3

Coarsely grate a third of the cauliflower into a bowl and set aside. Break the remaining cauliflower into florets, roughly 1¼ inches wide, and place them ina separate bowl with the cauliflower leaves, if you have any, and the onion. Toss with 2 tablespoons of the oil and ¼ teaspoon salt, then spread on a large parchment-lined baking sheet. Roast for about 20 minutes, until cooked through and golden brown. Remove from the oven and set aside to cool.

Step 4

Once cool, put the roasted vegetables in a large bowl with the remaining 3 tablespoons olive oil, the grated cauliflower and the parsley, mint, tarragon, pomegranate seeds, pistachios, cumin, lemon juice and ¼ teaspoon salt. Toss gently, just to combine, then transfer to a platter and serve.
