In a large saucepan over moderate heat, heat the butter and olive oil together. Sauté the spring onions and courgettes until caramelized. Add the spinach and stir until just wilted.

Drain in a colander and allow to cool to room temperature. Add the mint and seasoning.

Preheat the oven to 180 °C. Grease a shallow baking pan.

Loosely form 4 nests with the spinach. Pop into the baking pan and place in the oven for 5 minutes until the nests are heated through. Break an egg into each nest, return to the oven and bake until the eggs have set.

Serve with fresh dragon fruit.
