Ingredients
Burek Filling
 * 1 pkg dry yeast
 * 1/4 c lukewarm water
 * 1/4 tsp Sugar
 * 3 1/3 c all purpose flour
 * 1/2 tsp salt
 * 3/4 c lukewarm water
 * 1/2 melted butter
 * 9 eggs (slightly beaten)
 * 1/2 lb crumbled feta Cheese
 * 3 TB melted butter

Directions

 * 1) butter a large round pan (15-16 in) and set aside.
 * 2) Prepare yeast with 1/4 c lukewarm water and 1/4 tsp Sugar.
 * 3) Set aside. Sift flour and salt into large bowl, leaving a well in the middle.
 * 4) Add prepared yeast mixture into well. Begin mixing by hand and slowly add lukewarm water.
 * 5) Knead until dough forms a ball of medium consistency (approx 10 min).
 * 6) Divide dough into 14 equal parts, roll into round balls, cover and let stand for 1/2 hour.
 * 7) Melt 1/2 lb butter in saucepan.
 * 8) Roll out 4 balls into 6 in. circles, stack one on top of the other, brushing each layer with melted butter excluding the top layer.
 * 9) Let stand briefly, then roll out on slightly floured table to just a little bit larger than the bottom of your pan.
 * 10) Place in pan and brush top with melted butter.
 * 11) Mix filling and spread evenly to edge of pan.
 * 12) Now roll out one ball as thinly as you can; sprinkle with butter and gather it loosely into folds, and with a slight pull, elongate it.
 * 13) Starting from the center of the pan, place this dough over filling, circling it to look like a pinwheel.
 * 14) Repeat with remaining balls until you have reached the outer edge of your pan.
 * 15) Sprinkle generously with remaining butter.
 * 16) Cover with a tea towel and set Burek over a pan of very hot water for about 20 min.
 * 17) Bake in a preheated oven of 300 deg. for about 45 min or until nicely browned.
