01 - In a bowl, combine olive oil, minced garlic, chopped rosemary, thyme, lemon zest, sea salt, and black pepper. Thoroughly coat the lamb cutlets with the mixture, cover, and refrigerate for at least 30 minutes or up to 4 hours to intensify flavor.
02 - While lamb marinates, stir together Greek yogurt, fresh mint, parsley, lemon juice, ground cumin, salt, and pepper in a small bowl. Cover and chill until serving time.
03 - Preheat a grill or grill pan over medium-high heat.
04 - Remove lamb cutlets from marinade, allowing excess to drip off. Grill for 3 to 4 minutes per side for medium-rare doneness or adjust time to preferred cooking level. Remove from heat and let rest for 2 minutes.
05 - Plate the grilled lamb cutlets with a generous dollop of the mint yogurt sauce, garnished with lemon wedges and fresh mint sprigs.
