1. Preheat oven to 450 degrees Fahrenheit.
2. Line and grease a baking sheet. Spray cauliflower with nonstick cooking spray (this will help the seasoning stick) and toss with salt, za’atar, and olive oil. Spread in an even layer and spray again (this way you’ll get great roasted cauliflower using minimal oil). Bake for 25 minutes.
3. Meanwhile, whisk together dressing ingredients.
4. If serving this as a side, spread two ounces spring mix greens sporadically over your platter. Top with cauliflower and sprinkle with olives, pomegranates, parsley, and pistachios. Drizzle with creamy techina dressing. If serving as a salad, simply toss it all together in a bowl.
