5. M&S British Pork Belly Squares
These little bites of heaven are so moreish that the only problem you’ll have is wishing you’d bought more. The tender applewood and chestnut wood smoked pork belly is seasoned with smoked sea salt and pepper, then cut into squares. For the last five minutes of cooking, you pour over the sticky barbecue glaze.
