Chargrilled over glowing charcoal embers with an authentic smoky char, served with handcrafted accompaniments and savoury reductions.
Toss the halloumi, tomatoes, and peppers with olive oil, half the za'atar, the lemon juice, and garlic; rest 15 minutes.
Thread halloumi, tomato, and pepper alternately onto skewers.
Cook over medium-hot charcoal, turning, until the cheese is golden and the vegetables char slightly, 6 to 8 minutes.
Sprinkle with the remaining za'atar and the sumac.
Serve warm with flatbread and olive oil.
