This is the recipe from 
The Grecian Plate, a fantastic cookbook produced by the Greek Orthodox Church in Durham, NC.  I've made a few annotations in italics, because I do it slightly differently
- 3 (10-oz) packages of frozen chopped spinach, thawed (or lots of fresh spinach or dark leafy greens, kale is great!)
 
- 4 medium onions, chopped (I only use one large or two medium onions, usually)
 
- 6 whole green onions, chopped
 
- 1/4 cup olive oil
 
- 1/4 cup water
 
- 1 tsp salt
 
- 1/4 tsp pepper (I use fresh ground, and probably more like 1/2 tsp)
 
- 1/4 cup minced fresh parsley
 
- 1/4 cup minced fresh dill (optional)
 
- 1 tsp cream of wheat
 
- 5 eggs, beaten
 
- 1 cup cottage cheese (can be replaced by chevre for the lactose intolerant)
 
- 1 1/2 cups crumbled feta cheese
 
- 1 pound phyllo
 
- 1 to 1 1/4 cups butter, melted and warm (I don't usually use this much butter.  I start with one stick and add a bit of olive oil, that's usually enough for the whole pie)
 
 
- (If using frozen spinach) Drain spinach thoroughly in colander, squeezing out excess moisture.
 
- In a large skillet (if using frozen spinach, or a large non-reactive pot if using fresh greens), saute onions in olive oil over medium heat until tender, stirring constantly.
 
- Add spinach, water, seasonings and herbs; cook until liquid is absorbed.
 
- Sprinkle cream of wheat over top; cool.
 
- In a large bowl, combine eggs and cheeses; stir in spinach mixture, blending well.
 
- Set aside.
 
- Assemble pita (following directions are mine, the cookbook has a slightly different detailed set plus diagrams)
 
- Phyllo should be defrosted
 
- Set out two large cutting boards, and a large, wide baking pan.  Have the melted butter and a pastry brush ready.
 
- Carefully unfold the phyllo on the first board, cover with waxed paper and a very slightly damp towel (not too wet) -- this might not be required at all if you can work quickly enough so that the phyllo doesn't dry out.
 
- Working as quickly as you can, transfer a sheet to the second board, brush it lightly with the pastry brush and place the phyllo into the pan.  Overlap each sheet, allowing overhang on all sides.  Use about 2/3 of the phyllo in this manner.
 
- Pour the filling in, then fold the overhang over the top of it.
 
- Add the remaining phyllo sheets on top, this time not overhanging.
 
- Bake at 350 degrees for 55 to 60 minutes, or until golden brown (or you can freeze it, bake it later.
