Creating Greek Phyllo Meat Pie is straightforward if you follow these step-by-step instructions:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook the Meat: In a large skillet, heat a tablespoon of olive oil over medium heat. Add the chopped onion and minced garlic, cooking until the onion is translucent.
3. Add the Meat: Stir in the ground meat and cook until browned. Break up the meat with a spatula as it cooks.
4. Season the Filling: To the meat, add oregano, cinnamon, salt, and pepper, mixing well. Cook for an additional 2-3 minutes. Remove from heat.
5. Prepare the Filling: In a bowl, combine the cooked meat mixture with beaten eggs, parsley, and feta cheese (if using). Mix until everything is well incorporated.
6. Prepare the Phyllo: Take one sheet of phyllo pastry and place it on a clean surface. Brush the entire sheet lightly with melted butter.
7. Layer the Phyllo: Place a second sheet on top and brush with butter again. Repeat this process for a total of 5 layers.
8. Fill the Pie: Spoon the meat filling onto the center of the layered phyllo. Shape it into a rectangle, leaving space on the edges.
9. Fold Over the Pastry: Fold the edges of the phyllo over the filling, then carefully roll the pastry from one end to the other to form a log.
10. Bake the Pie: Place the pie seam-side down on a baking sheet. Brush the top with remaining butter and sprinkle sesame seeds if desired. Bake for 30-40 minutes until golden brown.
