Prepare the whipped hummus: Combine the hummus, Greek yoghurt, and Cape Herb & Spice Greek Style Lemon & Herb Rub in a large bowl. Whisk until smooth and well combined. Set aside.
Cook the pork chops: Prepare a medium-high heat braai. Drizzle the pork chops with olive oil and season generously with Cape Herb & Spice Greek Style Lemon & Herb Rub, rubbing to cover evenly. Braai the pork chops for 4-5 minutes per side, or until caramelised. Remove from heat and allow the chops to rest for 5 minutes before serving.
Make the chunky green olive salsa: In a medium-sized bowl, combine the chopped olives, diced cucumber, mint, sage, olive oil, vinegar, lemon juice, and minced garlic. Season with salt and pepper to taste. Mix well, adjusting the seasoning if necessary.
To serve: Spread the whipped hummus evenly across a large serving platter. Arrange the pork chops on top and spoon over the chunky green olive salsa. Garnish with roasted pine nuts and crumbled feta.
