Serbian Spinach and Cheese Burek with Hand-Kneaded Dough

Method

1. In a large bowl, mix spinach, crumbled feta, and mozzarella. Set aside.
2. In a separate bowl, combine flour and salt. Gradually add warm water and olive oil, mixing until a dough forms. Knead for 10 minutes until smooth and elastic.
3. Let the dough rest for 30 minutes in a warm place.
4. Roll out the dough on a floured surface to a thickness of 1/8 inch (3mm).
5. Cut the dough into 12 equal squares.
6. Place a spoonful of the spinach and cheese mixture in the center of each dough square.
7. Fold the dough over the filling to form a triangle, pressing the edges to seal.
8. Place the filled dough triangles on a baking sheet lined with parchment paper.
9. Bake at 375°F (190°C) for 20-25 minutes until golden brown and crispy.
10. Let cool slightly before serving.
