Caramelised Roasted Pork Belly with Pickled Mustard Greens

WHENEVER I MAKE ROAST PORK I ALWAYS MAKE MORE THAN ENOUGH SO I CAN THEN USE IT THE NEXT DAY TO MAKE THIS DISH. I LEARNT THIS FROM MY GRANDMOTHER, WHO NEVER WASTED A THING. IF YOU DON’T HAVE ANY LEFTOVER PORK AND YOU DON’T FEEL LIKE MAKING IT YOURSELF, YOU CAN BUY PIECES OF ROAST PORK FROM ASIAN BARBECUE SHOPS. FOR THE PICKLED MUSTARD GREENS, TURN TO FOR A RECIPE OR YOU CAN FIND THESE READY-MADE IN ASIAN MARKETS.
