Add the potatoes and a cup of water to your skillet pan. Leave the lid on and turn up to a high heat.
In a small food grade bag/bowl or container, add all the ingredients for the marinade. Mix well and add the lamb cutlets making sure they are well coated. Cover and leave for 20 minutes.
Whilst the lamb is marinating and the potatoes are steaming make the mint sauce by adding all the ingredients to your manual food processor and blitz thoroughly.
After the 20 minutes have passed for the marinating of the lamb, remove the lid from the skillet pan. All the liquid should have evaporated by now but if not pour away any remaining liquid. Add the lamb cutlets to the pan and cook over a high heat for 3 minutes each side. Turn the potatoes after 3 minutes too to get them crispy all over.
Serve on a bed of rocket and drizzle with your fresh mint sauce.
