Add vanilla bean and seeds and 100ml water (be careful, caramel will spit), stir to combine, then add pineapple and turn occasionally until caramelised (3-4 minutes). Remove pineapple and set aside. Add lime juice and rum to pan and stir to combine.
To serve, divide pineapple among bowls, top with a dollop of vanilla yoghurt, drizzle with pan juices and scatter with mint.
