Step-by-step instructions

1. 1

   Preheat the oven to 200 °C/180 °C with convection/gas 6. On a lightly floured surface, roll out the puff pastry to a size slightly smaller than an A4 rectangle. Transfer it to a baking tray, brush with beaten egg and bake for 20 minutes or until golden.

2. 2

   Meanwhile, melt the butter in a skillet over medium heat. When it begins to foam, add the onion with a pinch of salt. Cook, stirring regularly, for 10 minutes until softened. Add the balsamic vinegar and cook another 6–8 minutes until it becomes sticky and caramelised.

3. 3

   Spread the onion mixture onto the puff pastry, then arrange the courgette strips and pieces of goat cheese. Return to the oven for another 15 minutes until the cheese bubbles. Serve with salad.
