A vegetarian Christmas treat from Scandinavian chef Signe Johansen .It can be scaled down for two to three people.Use one sheet of filo per person and either make smaller pies, using a large muffin tin tray or small pastry tins, or simply place the filling in the middle of the pastry and fold over each layer, making sure to brush oil or melted butter on the exterior and base of the filo so it bakes to a crisp, golden finish.
