Prepare the Kefta Mixture: In a large bowl, combine the ground lamb, parsley, onion, garlic, cumin, paprika, cinnamon, coriander, cayenne pepper, salt, and pepper. Mix well until all the ingredients are evenly distributed.
Shape the Kefta: Take a small amount of the lamb mixture and shape it into an oval or a round meatball. Continue this process until all the mixture is used, placing the kefta on a plate.
Cook the Kefta: Heat a grill pan or skillet over medium-high heat. Cook the kefta for about 4-5 minutes on each side or until they are well browned and cooked through.
Prepare the Harissa Sauce: While the kefta cooks, whisk together olive oil, harissa paste, lemon juice, and honey in a small bowl. Adjust seasoning with additional lemon juice or honey to balance the spiciness and sweetness.
Make the Mint Yogurt: In another bowl, combine Greek yogurt, chopped mint, lemon juice, and a pinch of salt. Stir until well mixed.
Serve: Plate the kefta and drizzle with the harissa sauce. Serve the mint yogurt on the side for dipping or spooned over the kefta.
