Boil the chickpeas until soft. Strain, keeping a little of the liquid and whole chickpeas for garnish. Using a food processor, blitz the chickpeas with garlic and sesame seeds in a little of the liquid and olive oil. Season with salt, pepper and lemon.
Season the lamb loin chops with spices. Leave to marinade for 15 minutes. Heat oil in a non-stick pan then fry the chops for 3 - 4 minutes each side until medium rare.
If sharing, arrange the hummus on a large platter and top with the lamb loin chops. Garnish with the red onion, cherry tomatoes, herbs, sumac, sesame and chickpeas. Then season with lime and a little more olive oil.
