Spinach Boureks using pizza dough

I already posted a bourek (meat filled) recipe with filo pastry and meat filling.
Here I am using pizza dough and spinach. You can buy ready-made frozen pizza or roll dough from a supermarket or make it yourself. I am providing my recipe if you choose to make it yourself.
They make excellent lunches.

For 12 boureks
Ingredients
2 bunches spinach (stems removed) washed and chopped
1 tablespoon olive oil
1 tablespoon butter
2 french shallots or 1 small onion chopped
4 garlic cloves crushed
4 eggs + 1 yolk
Salt, pepper
Pinch nutmeg
1.5 cup grated cheese such as emmenthal, or feta

Directions
Sauté the onion with the olive oil in a saucepan over medium heat until translucent, around 10 minutes.
Add the garlic crushed, salt and spices and saute for another minute. Be careful not to let the garlic burn.
Add the butter and the spinach. Season and continue cooking until the liquid from the spinach is absorbed.
Remove from the heat and add the cheese. Mix well. Put aside and let cool Beat the 4 eggs and cook in omelette until just set.

Separate the dough in 6. Using a rolling pin, roll out each piece in a rectangle around 5 inches wide and 1/8 inch thick. Cut 8 inches long rectangles (approximately.)
Place your filling near the bottom edge of each rectangle leaving space for sealing, add a piece of omelette on top.
Fold the sides of the sheet over the filling to give it a moon shape. Moisten the edge to seal it.
Put aside, covered with a towel.
Repeat with remaining dough until you have used all the filling or all the dough.
Mix the egg yolk with one tablespoon of milk and brush the boureks with this mixture to give them a nice golden colour.
Cook in the oven 20-25 mn at 400F

Homemade Dough
For 12 boureks
4 cups flour
2 tablespoons margarine (or 1 margarine and 1 olive oil)
2/3 cup milk
2/3 cup water
1.5 teaspoon salt
1 teaspoon sugar
1 tablespoon yeast

Warm the milk in a small bowl with 1 teaspoon of sugar. Add the yeast, mix and let sit 10-15 minutes or until it becomes foamy.
Put the flour and salt in the food processor and mix for few seconds.
Add the flour, salt and margarine (or margarine and oil), mix to incorporat.e
With the machine still running, pour the yeast into the flour, then the water. Keep the food processor running for 2-3 minutes.
Remove the dough from the food processor and put it into a slightly oiled bowl. Cover and let it rest in a warm place for 15-20 minutes.

Note : I use a food processor to make the dough, but you can make it by hand, it doesn't require a lot of kneading.
