01 - Preheat the oven to 400°F for roasting the vegetables.
02 - In a large bowl, combine sweet potato, eggplant, bell pepper, zucchini, and red onion. Add olive oil, cumin, coriander, cinnamon, smoked paprika, salt, and pepper. Toss until vegetables are evenly coated with spices.
03 - Spread vegetables in a single layer on a large baking sheet. Roast for 30-35 minutes, stirring halfway through cooking, until vegetables are golden brown and tender.
04 - While vegetables roast, heat 1 tablespoon olive oil in a nonstick skillet over medium heat. Add haloumi slices and cook for 2-3 minutes per side until golden brown and slightly crispy.
05 - Transfer roasted vegetables to a serving platter. Arrange seared haloumi slices on top of the vegetables.
06 - Scatter pomegranate seeds, chopped pistachios, mint, parsley, and lemon zest over the dish. Serve immediately while warm, with Greek yogurt or tahini sauce on the side if desired.
