Add the ground meat to a large bowl along with all of the ingredients and 2.5 teaspoons of salt. Mix well and allow to sit in the fridge for at least 1 hour, ideally 3-24 hours.
Preheat grill to medium-high, or if using a traeger grill like I did, heat to 400F with the grill grate at the lowest setting. Form the kebab mixture into 4 equal portion and wrap the meat around the skewers. Make sure the meat is evenly spread out from top to bottom of the skewers.
Spray the skewers with ghee spray and place oiled side down on the grill and close the lid. Cook for 8 minutes, spray the other side with more ghee, carefully flip kebabs, close the lid, and cook another 8 minutes. Remove from grill and allow to rest 5 minutes before serving.
