In a large bowl, combine the minced lamb, grated onion, garlic, red chili flakes, paprika, parsley, and salt.
Mix thoroughly for 8–10 minutes until the mixture becomes sticky and well combined.
Cover and refrigerate for at least 1 hour to allow the flavors to develop.
Divide the mixture into equal portions and press it firmly around wide metal skewers into long, flat kebabs.
Preheat a charcoal grill or oven to 220°C (425°F).
Grill the kababs for 10–12 minutes, turning occasionally until evenly browned and cooked through.
Remove from the grill and let the kababs rest for 2 minutes before serving.
Serve hot with Turkish flatbread, grilled tomatoes, green peppers, sliced onions, yogurt, and lemon wedges.
