Step 1: In a medium bowl, combine the olive oil, lemon juice, soy sauce, ground cumin, ground coriander, paprika, garlic powder, salt, and black pepper. Whisk until all ingredients are well combined to form the marinade.
Step 2: Add the lamb chops to the marinade, ensuring they are evenly coated. You can use a shallow dish or a resealable bag. Let the lamb chops marinate for at least 30 minutes at room temperature, or for 2-4 hours in the refrigerator for deeper flavor.
Step 3: Preheat your grill to medium-high heat. Lightly oil the grill grates to prevent sticking.
Step 4: Place the marinated lamb chops on the preheated grill. Grill for 3-4 minutes per side for medium-rare doneness, or longer if you prefer them more well-done. Use a meat thermometer to check for your desired internal temperature (e.g., 130-135°F for medium-rare).
Step 5: Once cooked, remove the lamb chops from the grill and let them rest on a cutting board for 5-10 minutes. This allows the juices to redistribute, resulting in more tender meat.
Step 6: Garnish the rested lamb chops with chopped fresh parsley and crumbled feta cheese. Serve immediately with optional fresh parsley sprigs and lemon wedges for a bright finish. Enjoy!
