Preheat the oven to 375F.
Split the baguette vertically into halves without cutting all the way through. Pull out some of the bread on both halves to create “ditches” to hold the fillings in place.
Spread the mayonnaise on the “ditches” then scatter the chopped barbecued pork on the bottom half of the baguette.
Sprinkle with herbed salt.
Toast in the oven for about seven minutes or just until the bread turns a bit crisp and the meat is heated through.
Take the bread out of the oven. Spread the mango cubes on top of the meat followed by the red onion slices and, finally, the parsley.
Fold the baguette to cover the fillings, cut into three to four portions and serve.
That is sandwich with a little imagination.
