Preheat the oven to 400° F. Line a baking sheet with parchment paper.
In a large bowl toss the cauliflower florets with the olive oil until well coated, then add cumin and sea salt and toss again.
Spread out the cauliflower florets on the baking sheet. Roast for about 20 minutes, turning once, until the edges are brown and caramelized.
When finished, gently mix the warm cauliflower with the dressing until well coated. Add the currants, olives, and parsley and stir to combine. Taste and add more dressing or salt, if desired.
