  1. Heat the oil in a large saucepan, over a medium heat. Add the onions and some seasoning, then cook, covered, for 25 mins, stirring occasionally. Remove the lid and continue to cook for 20 mins, stirring occasionally. Add the garlic and thyme and continue to cook for 5 mins, stirring, until starting to caramelise and turn golden.
  2. Preheat the oven to gas 6, 200°C, fan 180°C. Unroll the pastry, keeping the paper underneath. Transfer to a large baking sheet and, using a sharp knife, score a border about 1.5cm in from the edge. Spoon over the onions, keeping inside the border. Place the anchovies on top in a diamond pattern and put the olives in the gaps. Bake for 25-30 mins until golden and crisp. Serve garnished with the remaining thyme and a green salad, if you like.
