Peruvian pork roll (pan con chicharron)

In Peru, chicharrón refers to succulent pork, which is braised and then fried in its own fat. It forms the basis of this popular snack, piled onto a roll with fried sweet potato and a spicy onion salsa. We’ve added a sauce made from Peru’s ubiquitous aji amarillo chilli, and have used pork belly roasted in the oven for ease.
