On a floured surface, roll the dough into a 14x10 inch rectangle. You could also do this directly on a baking sheet, but I find it easier to do it on a big flat surface and then move the roll.

Spread cream cheese all over the rectangle.

Mix the drained spinach, cottage cheese, egg, feta and seasonings in a bowl, then spoon lengthwise across the center of the rectangle.

Dampen edges of rectangle with a little water, then fold the long sides up so they meet in the middle, covering the spinach. Pinch to seal and tuck in ends.

Let rise for 45 minutes. Brush with a mixture of beaten egg and water

Bake at 375 for about 30-35 minutes or until golden brown.
