In a large plastic or glass bowl, whisk together 4 Tbsp of olive oil, 2 Tbsp of lemon juice, 2 Tbsp of soy sauce, 1 Tbsp of honey, 1 tsp of dried oregano, 1 tsp of dried thyme, 1 tsp of ground cumin, ½ tsp of ground coriander, ¼ tsp of lemon myrtle or wattleseed (if using), and Salt and pepper to taste until well combined.
Add the 8 bone-in lamb loin chops or cutlets to the marinade, ensuring they are evenly coated.
Cover and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavour infusion.
Preheat your barbecue or grill to medium-high heat. Use olive oil for brushing the grill grates or hotplate to prevent sticking.
Remove the lamb chops from the marinade, discarding any excess.
Cook for 3-4 minutes per side, or until cooked to your desired level of doneness.
