Cut the lamb kidneys into bite-sized pieces and place them in a bowl.
In a separate bowl, mix together the minced garlic, olive oil, oregano, paprika, salt, and pepper.
Pour the marinade over the lamb kidneys and toss to coat evenly. Cover and refrigerate for at least 30 minutes to marinate.
Preheat the grill or grill pan over medium-high heat.
Thread the marinated lamb kidney pieces onto the soaked skewers.
Grill the skewers for about 3-4 minutes per side, or until cooked to your desired level of doneness.
Serve the lamb kidney skewers hot, garnished with fresh herbs or a squeeze of lemon juice, if desired.
Enjoy!
