Ingredients

  • 5 tablespoons butter cut into pieces
  • 1 1/4 cups flour plus extra for dusting
  • 1 teaspoon salt
  • 1 egg plus 6 egg yolks
  • 2 zucchinis thinly sliced
  • 4 tomatoes thinly sliced
  • 1 cup milk
  • 5 tablespoons oregano finely chopped
  • 3 spring onions trimmed and thinly sliced
  • 4 ounces gouda cheese grated
  • 4 ounces pitted black olives sliced
  • 1/4 pound wild mushrooms small, cleaned

Method

  • For the dough, rub the butter, flour and salt together. Mix in the egg and knead until smooth. Shape into a ball then wrap in foil and chill for 30 mins.
  • Preheat the oven to 400°F. Roll out the dough on a lightly floured work surface to make a 10 inch diameter circle. Lay in a greased 9 inch diameter loose-bottomed tart pan and gently press into the edges.
  • Arrange the zucchini and tomato slices in the pan on top of the dough. Whisk the milk and egg yolks together, stir in the oregano and season. Pour the egg mixture on top of the zucchini and tomatoes and sprinkle with spring onions. Mix the cheese, olives and mushrooms together and spread on top. Bake for 20-25 mins until golden. Serve hot or cold.
