Preheat the oven to 200C/400F/Gas 6.
To make the toffee bananas, melt the butter in an ovenproof frying pan over a medium heat. When the butter foams add the sugar, lime juice and chopped nuts. Continue to cook for 2-3 minutes, until thickened.
Add the banana and stir well to coat in the mixture. Transfer to the oven and bake for five minutes.
To make the vanilla yoghurt, place the yoghurt and the vanilla seeds into a small bowl and mix well.
To make orange glaze, heat a frying pan and add the honey, vanilla pod and seeds and the orange juice. Stir together well and simmer until the mixture reaches a thick, syrupy consistency.
To serve, place the toffee bananas on a plate, drizzle the orange glaze over and spoon the vanilla yoghurt onto the side.
