Spinach-and-greens pastries

For the puff pastry:
    5 tablespoons Sitia Extra Virgin Olive Oil
    1/2 cup water
    1 - 2 eggs
    1 teaspoon salt
    1 lb self-rising flour
 
For the filling:
    4 tablespoons Sitia Extra Virgin Olive Oil
    2 lbs spinach
    1 medium onion or 5 spring onions, finely chopped
    1 cup finely chopped parsley
    1/2 cup grated kefalotyri or crumbled feta cheese
    1/2 teaspoon salt
    1/2 teaspoon pepper

Prepare the dough: Beat eggs, add olive oil, water, salt and flour, little by little. Knead till you have a hard and elastic dough. Cover and refrigerate for 30 minutes.

Prepare the filling: Wash and chop spinach, dip in boiling water for 5 minutes and then drain completely. Heat olive oil in a saucepan and soften onion. Add spinach and stir a few times until juice has evaporated. Put in parsley, salt and pepper, remove from heat and stir in kefalotyri cheese or feta cheese.

Take pieces of dough the size of a walnut and roll each one out into a small circle. Place 1 teaspoon filling on 1 half and cover with the other half. Press the edges down with a fork to close firmly, baste with olive oil or beaten egg white and bake in moderate heat until golden brown, about 25 minutes.
