Prepare the Filling
Heat a pan over medium heat and melt a little butter.
Sauté the chopped onion until soft and golden.
Add minced meat, dried basil, salt, and black pepper. Cook until fully browned.
Remove from heat and let cool slightly. Stir in the grated cheese, chopped parsley, and boiled eggs.
Assemble the Pastry
Preheat the oven to 200°C (400°F).
Roll out the puff pastry on a floured surface and cut into desired shapes (squares, rectangles, or circles).
Place a spoonful of filling in the center of each piece. Fold over and press the edges with a fork to seal.
Brush the tops with beaten egg and sprinkle with sesame seeds if desired.
Bake to Perfection
Arrange the pastries on a lined baking sheet.
Bake for 20-25 minutes or until the pastry is golden brown and puffed up.
Serve and Enjoy
Let the pastries cool for a few minutes before serving.
Enjoy warm, either as a snack or paired with a fresh salad for a complete meal.
