Cheesy spinach inside golden flaky yummy puff pastry!
Bring a large pot of salted water to a boil. Add spinach and cook just until wilted. Drain spinach and when cooled, squeeze out liquid using a dish towel. In a bowl, add the spinach, both cheeses, rosemary, salt, pepper and lemon zest. Mix well.
Unfold puff pastry sheets onto a lightly floured counter. Roll both out to a 12 inch square. Using a 3 inch round cutter (can use jar cover), cut out 30-32 circles.
Beat eggs in a bowl. Brush half of each circle with egg. Top each circle with 2 tablespoons of the spinach/cheese mixture and fold puff pastry over. Using a fork, crimp each half circle to seal.
Preheat oven to 375 degrees F.
Brush tops with the remaining egg and sprinkle with sea salt. Bake for approximately 20 minutes until golden brown.
