Tika kabab (tika kebab)

Instructions

1. Cut the lamb into even cubes of about 3 cm, removing fat and sinew.
2. Grate the onions, then mix them with the meat, oil, vinegar, salt, pepper and spices.
3. Cover and leave to marinate in the fridge for at least 4 hours, ideally overnight.
4. Thread the cubes onto skewers, pressing them together lightly and alternating with bell peppers if you're using them.
5. Grill over high heat for 10 to 12 minutes, turning regularly, until the edges are golden.
6. Sprinkle with sumac and chopped parsley.
7. Serve with rice or flatbread.
