Heat olive oil in a frying pan over medium heat.

Add the diced onion and cook until translucent, about 5 minutes.

Stir in the minced garlic, cumin, paprika, salt, and pepper, and cook for a minute.

Add the ground beef to the pan and cook until browned, breaking it apart with a spoon, about 8 minutes.

Stir in the chopped olives and parsley.

Roll out the puff pastry on a floured surface to a thickness of about 1/8 inch.

Cut out circles from the pastry using a round cutter or a glass, each about 5 inches in diameter.

Place a spoonful of the beef mixture in the center of each pastry circle.

Fold the pastry over the filling and crimp the edges with a fork to seal.

Brush the tops with the beaten egg, then bake at 400°F for 25 minutes or until golden brown.
