Place the lamb chops in a baking dish.

In a bowl, combine olive oil, garlic, rosemary, mint, orange juice, Essence (if available, otherwise a general spice blend), salt, orange zest, and pepper.

Pour the marinade over the chops, ensuring both sides are well coated.

Let the lamb chops marinate at room temperature for 60 minutes or refrigerate, covered, for up to 4 hours.

Preheat a grill to medium-high heat.

Place the marinated lamb chops on the preheated grill.

Grill for about 2-3 minutes per side for medium-rare, turning once during the cooking process.

Remove the grilled lamb chops from the grill.

Serve the grilled lamb chops immediately with the prepared Mint Pesto.

To prepare the Mint Pesto: Pick mint leaves from stems.

Place mint leaves in a blender carafe with Parmesan cheese, toasted pine nuts, and garlic.

Press the ingredients down into the base of the blender.

Secure the lid on the carafe and remove the feed tube.

Turn the blender on to a low speed.

Slowly drizzle olive oil through the feed tube while pulsing the blender to incorporate the ingredients.

Once blended, season the pesto with salt and pepper.

Pulse the blender again to thoroughly incorporate the seasoning.
