4 tablespoons mashed feta cheese
4 tablespoons grated parmesan cheese
1 lb. phyllo dough**
3 eggs, beaten
3 packages of frozen chopped spinach
black pepper
1/2 cup (1 stick) of butter melted
1 baking pan (10 x 17 x 2 inch)

** The best kind is the kind that is freshly made. It can be purchased from Poseidon Bakery in Manhattan. The refrigerated or frozen kind, such as Apollo or Krinos, is fine.

Preheat oven at 350 º Fahrenheit.

1. Melt butter.

2. Defrost spinach. If you defrost in the microwave, be careful not to cook the spinach. You just want to be able to break the defrosted spinach into pieces with your hands. Break the spinach and if there is still ice, defrost some more. When all the ice is melted, squeeze the spinach of all the water as much as possible using a sieve and/or your hands and letting the water drain out.

3. Put the spinach in a bowl. Add the beaten eggs and feta and parmesan cheeses. Mix with a large spoon.

4. At a large table, arrange the bowl of melted butter, the baking dish and the phyllo dough and have a few dampened paper towels on hand. Roll out the phyllo dough

5. Using a pastry brush, generously brush some butter onto the bottom of the baking tray. Place one sheet of the phyllo dough. Since the sheet is larger than the baking dish, with a knife cut the sheet and put aside. Brush some more butter on the sheet in the dish. Put the sheet you put aside on top. Brush some more butter. Repeat until you have used up half of the quantity of sheets.

6. Spread and evenly distribute the spinach filling on the phyllo dough in the dish.

7. Add the remaining sheets of phyllo dough as in step 5.

8. Generously butter the last sheet of phyllo dough.

9. With a pizza cutting wheel or a very sharp knife cut the phyllo dough into squares or diamonds.

10. Place in oven for 30-40 minutes or until bottom and top are golden brown.

Options:

You can use a plain cheese filling:

1 lb. feta cheese
4 oz cream cheese (softened at room temperature)
8 leaves of fresh mint (or more depending on taste), chopped
Cayenne pepper, black pepper

Mash the feta cheese with the back of a fork until crumbled. With a spoon, mix the cream cheese with the feta cheese. Add the mint and some dashes of cayenne pepper.
Mix all very well. Proceed beginning with steps 4-10 above.

You can make individual triangles (more time consuming):

Take an individual sheet and cut in half from the center of the short side, down the length of the sheet.
Fold one of the halves in half so that you have a long strip.
Brush with melted butter.
Spoon some filling at one end, but not too much.
Fold that end so that you have a triangle.
Keep folding until you have a puffy triangle & brush with butter.
Place on a cookie tray and repeat for the rest of the phyllo dough.
Put in a 350 degree oven until golden brown.
