Spinach Feta Turnovers

A delicious recipe from Every Day Food magazine.

2 tbsp olive oil
2 medium onion
2 garlic cloves, minced
4( 10oz.)boxes spinach, frozen
2 C crumbled feta cheese
2 tbsp lemon juice, fresh
1/8 tsp cayenne pepper
salt and pepper to taste
1 egg
1 box(17.3oz.)oz puff pastry

Directions :
Thaw spinach and squeeze out the moisture.
Thaw puff pastry, but keep cold
In a medium skillet heat oil and then sautee onions and garlic until tender, 5-7 minutes. Transfer to a large bowl and mix in spinach, feta, lemon juice and cayenne. Season filling with salt and pepper, then set aside.
Preheat oven to 375F. On a lightly floured work surface, roll out each portion of dough into a 12" square; cut each into quarters to form 8 equal squares.
Dividing evenly, spoon filling onto center of each square. Fold the edges over to form a triangle and press firmly to seal. With a floured fork, crimp edges.
Transfer turnovers to baking sheet, brush tops with egg mixture (1 egg beaten with 2 tbsp water) for a golden glaze. Bake until golden and puffed, about 35-40 minutes, rotating baking sheet halfway through.
