I think the latest Morrisons mag had this featured. .Pretty sure it's just shoulder of pork that's slow cooked and then 'pulled' with a fork to give shredded servings, rather than sliced.
And sorry - it was the latest Aldi Mag that had it in 'Pulled Pork Shoulder with Ginger & Black Pepper'. It looks delish - pork would always be my last choice of meat / joint but I might try this one
