Creating Cheesy Beef and Mushroom Pita Pockets is straightforward and enjoyable. Follow these steps for a delicious outcome:

1. Heat Oil: In a large skillet, heat the olive oil over medium heat.
2. Cook Onions and Garlic: Add the chopped onion and sauté until translucent, about 3-4 minutes. Add minced garlic and cook for another minute.
3. Brown the Beef: Add the ground beef to the skillet. Break it apart with a wooden spoon and cook until browned, approximately 5-7 minutes.
4. Add Mushrooms: Stir in the chopped mushrooms and cook for 3-4 minutes until they soften.
5. Season: Add soy sauce, Worcestershire sauce, oregano, salt, and pepper. Mix well and cook for another minute for flavors to meld.
6. Incorporate Cheese: Remove the skillet from heat and stir in ¾ cup of shredded cheese until melted and evenly combined.
7. Prepare Pitas: Slice the pita pockets in half, creating a pocket.
8. Stuff the Pockets: Generously fill each pocket with the beef and mushroom mixture.
9. Top with Cheese: Sprinkle the remaining cheese on top of the filled pitas.
10. Bake (Optional): For a crispy texture, place the stuffed pitas on a baking sheet and bake in a preheated oven at 375°F (190°C) for 5-7 minutes until the cheese is bubbly.
11. Garnish and Serve: Remove from the oven, garnish with chopped parsley if desired, and serve warm.
