Preheat the oven to 400 degrees F.
Toss the sliced carrots and very dry chickpeas with oil and za'atar spices until evenly coated. Spread into a single layer on a baking sheet.
Roast for 10 minutes, stir or flip, and roast another 10-15 minutes, until the carrots have begun to caramelized and the chickpeas are crispy.
Heat a skillet over medium heat and lightly coat the bottom of the skillet with oil. Add the halloumi slices and cook on both sides until golden brown.
Drizzle with honey and cook for about 30 seconds, then remove from heat.
In a small bowl, whisk together the tahini, lemon juice, honey and enough water to thin into a pourable dressing.
In a large bowl or platter, combine the roasted carrots, chickpeas, hot halloumi, almonds and pistachios.
Drizzle with dressing and toss gently.
Top with fresh parsley and serve with lemon wedges.
