Step 1

Preheat oven to 375 degrees F and line a large baking tray with parchment paper. Set aside.

Step 2

Crumble the goat's cheese and set aside.

Step 3

In a medium skillet set over high heat, add the olive oil and the sliced onions. Cook over high heat until they start to brown, about 5 minutes. Reduce heat to medium low and all the onions to continue to cook for a further 15 - 20 minutes or so until they become a deep golden colour and are really soft. Stir occasionally through the cooking process. Remove from heat.

Step 4

Cut the pastry into 12 equal squares and place on the baking tray. Brush the edges of the pastry with the whisked egg. Place a spoonful of the onions in the centre of each pastry square. Bake for around 15 minutes or until golden and puffed. Remove from oven.

Step 5

Top with crumbled cheese, balsamic reduction and a sprinkle of parsley. Serve straight away.
