01 - In a bowl, whisk together olive oil, minced garlic, rosemary, thyme, lemon zest, sea salt, and black pepper. Coat lamb cutlets thoroughly with the marinade. Cover and refrigerate for a minimum of 30 minutes, up to 4 hours for enhanced flavor.
02 - Combine Greek yogurt, chopped mint, parsley, lemon juice, ground cumin, salt, and pepper in a small bowl. Mix well, cover, and refrigerate until serving.
03 - Heat grill or grill pan over medium-high heat, ensuring it is properly preheated before cooking.
04 - Remove lamb from marinade, allowing excess to drip off. Grill cutlets for 3 to 4 minutes per side for medium-rare doneness or adjust timing according to preference. Remove from heat and let rest for 2 minutes.
05 - Plate lamb cutlets alongside mint yogurt sauce. Garnish with lemon wedges and fresh mint sprigs before serving.
