Spinach pie

A friend of mine sent me this recipe, I cut it in half otherwise we would be eating this for 2 weeks! So here it is as the full recipe: 10oz. feta cheese, 1-16oz, cottage cheese, 1 onion diced and sauteed, 4 eggs, 4- 10oz packages of spinach, thawed and drained, mix all the above ingredients in a bowl. This makes enough filling for 2- 9x13 pans. 1 pkg. filo dough, thawed, should be 2-20 sheets of filo dough, melt 2 1/2 sticks of butter, greased pan with the butter, carefully unwrap filo dough and lay down one sheet and using a basting brush spread the butter on that sheet, lay down another sheet and butter, continue until you have used 10 sheets of filo dough, spread 1/2 filling on top of the butter dough, then start with dough sheets again with the buttering, until you have used up all the sheets(another 10 sheets). Cut into squares before baking. Sprinkle with Parmesan cheese, bake at 350 for 45 minutes. Enjoy!! It is really good!!! Thanks Michelle! Blessings!
