Place the potatoes (in their skins but diced) into the Instant Pot and cook for 15 minutes on the steam function. Make sure the potatoes are in the steamer basket and that you have added a cup of water to the bottom. Then of course set it to sealing so that it will go to pressure.
While the potatoes and cooking peel and thinly dice the carrots and the onion.
Remove the potatoes from the Instant Pot and place them in a mixing bowl that would be of a decent size for mashing your potatoes.
Save the liquid from the bottom of the Instant Pot and put it to one side for using later.
Place the carrots and onion in the Instant Pot with a tablespoon of olive oil and cook on the sauté setting for 3 minutes or until the onion has softened.
Add the lamb and green beans to the mixture, mix well and continue to sauté for 2 more minutes.
Add the lamb stock, the seasoning and bring to the boil.
While it is coming to the boil make your mash. Add to the potatoes the coconut oil, 50ml of the potato stock, salt and pepper and a couple of tablespoons of the mince liquid to give it extra flavour.
Stir a few times and transfer the mixture into the bottom of four ramekins. Use a big spoon with holes in to transfer the meat as then it will stop you having a huge amount of liquid in the bottom of the ramekins.
Add the mash to the top. Cook the ramekins in the Airfryer for 5 minutes at 200c.
Serve.
