Coat the pastry with concentrated tomato juice and arrange first the turkey or ham slices and olives, then the crumbs of feta cheese and the grated gouda cheese. On the top arrange the chopped mushrooms and red or green pepper, last the tomato and oregano. Certainly you may put any other ingredients of your choice. Bake for ½ hour at 200 degrees Celsius.
