Onion, Sage, and Gruyere Tart

Preheat the oven to 190C. Put the oil in a pan, and fry the sage leaves for a couple of minutes until crisp. Remove with a slotted spoon, and put to one side.
Add the onions to the same pan, and cook on a low heat for 20 minutes, until softened, browned, and caramelised. Set aside.
Roll out the puff pastry, and lay on a lined baking tray. Top with the caramelised onions, leaving a border around the edge. Add the potato pieces, and sprinkle over the grated gruyere. Season with salt and pepper, then pop in the oven for 25 minutes. Remove from the oven when golden brown, then garnish with the sage, and serve.
