Albanian spinach pie (Byrek me spinaq)

I took a break from politics to make this.


Filling:
2 teaspoons red pepper flakes
1 medium finely chopped onion
1 pound chopped feta cheese
30 ounces frozen chopped spinach defrosted
1 egg

Dough:
salt, 1 egg, 4 cups flour, about 1-1/2 cups water
6 tablespoons butter (to spread between layers)

Saute the onion (I added some of the spinach juice and sauteed it dry). Add the other ingredients.

Mix salt, flour, egg, water, knead, roll into a roll, cut in half, then each half into five pieces. Roll each into a ball. Roll one ball to size of small plate, put it on a square of wax paper, brush it with butter. Repeat with the next four balls so you have a stack of 5 on your wax paper. Butter the top. Put in the refrigerator and do the other five. Chill for at least ten minutes.

Preheat oven to 360 degrees.

Take one of the dough stacks out of the fridge and roll it out thin, put it on your baking pan, I used a pizza pan about 15" in diameter. Spread the filling on it. Roll out the other dough stack, put it on top of the filling, crimp the edges. Press a 5" bowl with straight sides down in the center of the pie and cut around it. Cut a cross through the circle. Then use a pizza cutter to pre-cut serving size pieces radiating from the circular center. Glaze with an egg beaten with the remaining butter. Bake for at least 45 minutes
