Lift the lamb from the slow cooker and pour any juices into a jug (or gravy separator, if you have one). Use a couple of forks to shred the meat, discarding the bones, any gristly bits and large bits of fat that haven’t melted away. Pour off the fatty oil that has risen to the top of the juices, then toss the shredded meat with as much of the juice as you like. Taste for seasoning. Spread the warm flatbreads thickly with the garlic sauce, then top with piles of meat, veg, crispy fries and hot sauce, if you like. Wrap up and eat straight away.
