Instructions

Step 1: Heat a grill pan over medium-high heat. Slice 8 oz halloumi cheese into 1/2-inch thick pieces and brush both sides with 1 tbsp olive oil. Grill the halloumi for 2-3 minutes per side until golden brown and grill marks appear.
Step 2: Brush 2 pieces of flatbread with 2 tbsp olive oil and sprinkle each with 1 tbsp za'atar evenly. Place flatbreads on the grill pan and cook for 1-2 minutes per side until warm and slightly charred.
Step 3: In a medium bowl, toss 1 medium thinly sliced red onion with 1 tbsp sumac powder, 2 tbsp fresh lemon juice, 1/2 tsp black pepper, and 2 tbsp chopped fresh parsley. Let sit for 5 minutes to soften.
Step 4: To serve, place grilled halloumi on top of za'atar flatbreads and spoon sumac onions over the cheese. Serve warm as an appetizer or light meal.
