Preheat the oven to 200C/400F/Gas 6.
Using a meat mallet or rolling pin, flatten the pork to 2cm/¾in thick.
For the rub, mix the herbs and oil in a bowl, rub over the pork and season with salt and freshly ground black pepper.
Heat an ovenproof griddle pan and griddle the pork for 3-4 minutes on each side.
For the apple crust, place the breadcrumbs, chopped apple and cheese on top of the pork and place into the oven to bake for five minutes, or until golden-brown and completely cooked through.
Meanwhile, for the crackling, place the pork fat onto a baking sheet and bake in the oven for 15 minutes, or until crisp and golden-brown.
For the apple sauce, place the butter, sugar and apple pieces into a pan and cook over a gentle heat for 5-6 minutes until softened.
To serve, place the pork onto a plate along with the crackling and the apple sauce.
