Preheat the oven to 190C. Line a baking sheet with baking paper.
Roll the pastry out into two 6in circles. Place the pastry carefully onto the paper lined baking sheet. Crumble the goats cheese in the middle of each circle, leaving a 1 inch border all round. Arrange the tomatoes in an even layer over the goats cheese. Grind some black pepper over top and a bit of salt and sprinkle the olives evenly over all. Gently fold the edges of the pastry over top of the filling all the way around, leaving the middle open. Brush the top of the pastry with a little milk.
Bake in the heated oven for 15-20 mins until the pastry is golden and the filling is cooked. Drizzle with the olive oil and sprinkle with the basil strips. Serve with salad.
