Marinade the pork with some olive oil, garlic salt and rosemary. Leave for 20 minutes.

Grill the pork for a few minutes each side until cooked through.

Meanwhile, grill the apple slices turning to brown on both sides.

When just ready to serve, brush the buns with a little olive oil and toast.

Serve the pork loin steaks on the bun topped with the apple slices and coleslaw.
