Method
- Pat the lamb cubes dry with paper towels and place in a large bowl.
- Grate the yellow onion on the large holes of a box grater. Press the pulp through a fine mesh strainer over the lamb to capture the juice, then discard the pulp.
- Add the olive oil, yogurt, minced garlic, cumin, paprika, sumac, salt, and black pepper to the bowl. Toss until every cube is evenly coated. Cover and refrigerate 4 to 6 hours, no longer.
- About 45 minutes before cooking, light a chimney of hardwood charcoal. When the coals are fully ashed over and glowing, spread them in an even bed and let the grates heat for 5 minutes.
- Pull the lamb from the fridge and let it sit at room temperature for 20 minutes. Thread the cubes tightly onto flat metal skewers, leaving a quarter inch gap between each piece so they sear rather than steam.
- Thread the tomato halves and red onion wedges onto separate skewers. Leave the long green peppers whole to grill directly on the grate.
- Place the lamb skewers over the hottest part of the coals. Grill 8 to 12 minutes total, turning every 2 minutes, brushing lightly with melted butter on the final turn. The lamb should be deeply charred outside and just blushing pink inside, about 130 F.
- Add the tomato and onion skewers and the whole peppers to the grill during the last 6 minutes, turning until softened and blistered.
- Lay the lavash directly on a warm platter and rest the cooked skewers on top so the bread soaks up the juices. Tent loosely with foil for 3 minutes.
- Toss the thinly sliced red onion with chopped parsley and a heavy pinch of sumac. Slide the lamb off the skewers, scatter with the sumac onions, and serve immediately with the grilled vegetables and lavash.
