In a large bowl, toss together the cauliflower pieces, olive oil, curry powder, and ½ tsp of salt until well combined. Spread in a single layer on a baking sheet, and roast at 400 degrees until tender and beginning to brown, about 25 minutes. Stir once halfway through roasting to help keep even browning.
To make the tahini sauce, whisk together the yogurt, tahini paste, lemon juice, water, honey, cumin, and the remaining ¼ tsp salt. Add a bit more water to the sauce if you’d like a thinner consistency.
Divide the freekeh evenly between plates (or bowls, or what have you), top with equal amounts of arugula, roasted cauliflower, cashews, and golden raisins. Drizzle tahini sauce over top and serve immediately.
