Preheat your grill to a high heat. Place the mango on a baking tray and sprinkle with the brown sugar, chilli and lime zest. Drizzle over the lime juice, mix everything together, then place under the grill until the mango begins to brown.
Meanwhile, mix the yoghurt with the cinnamon.
When the mango has caramelised, divide between two bowls and spoon over the yoghurt. Sprinkle over the sliced mint and serve.
Instead of mango, you could use pineapple or apple.
