In a large bowl, combine minced meat, grated onion, garlic, red pepper flakes, paprika, sumac, cumin, black pepper, salt, olive oil, parsley, and chili paste.
Mix well using your hands until the mixture is fully combined and slightly sticky.
Cover and refrigerate for at least 30 minutes to allow flavors to blend.
Divide the mixture into equal portions and shape them onto skewers, pressing firmly to ensure they stick.
Preheat the grill or barbecue to medium-high heat.
Grill the kebabs for about 4-5 minutes on each side or until fully cooked and slightly charred.
Serve hot with pita bread, rice, grilled vegetables, and a side of yogurt sauce.
