Bring a pot of salted water to a boil. Add chopped green beans and blanch for 2.0 to 3.0 minutes until bright green and slightly tender. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for about 3.0 to 4.0 minutes until translucent.
In the skillet with the onions, add the cooked turkey, blanched green beans, turkey gravy, garlic powder, dried thyme, salt, and pepper. Mix thoroughly and cook for an additional 2.0 to 3.0 minutes until heated through. Remove from heat and stir in shredded cheese until melted and combined.
Roll out the thawed puff pastry sheets on a lightly floured surface. Cut each sheet into a 4x4 inch square (or your desired size, ensuring they fit your baking dish).
Place a generous spoonful of the turkey and green bean filling in the center of each pastry square. Fold the pastry over to create a triangle or rectangle shape, ensuring the edges are sealed.
Place the filled pastries on a parchment-lined baking sheet. Brush the tops with the beaten egg for a golden finish.
Bake in the preheated oven for 20.0 to 25.0 minutes or until the pastries are puffed and golden brown.
Remove from the oven and let cool for a couple of minutes. Serve warm, drizzled with extra turkey gravy and garnished with fresh chopped parsley.
