In a medium-sized mixing bowl, combine ground beef with finely chopped parsley and chosen spices. Mix thoroughly until evenly incorporated, creating a flavorful filling. Let it meld for about 5 minutes.

Take pita breads and slice each in half to create pockets. Spoon the meat mixture into each half, pressing down slightly to ensure it stays contained. Avoid overfilling.

Preheat your grill or oven to medium heat (about 375°F / 190°C). For grilling, brush the grate lightly with olive oil. For baking, arrange stuffed pitas on a lined baking sheet.

Place the stuffed pitas on the grill or into the oven. Grill for about 10-15 minutes, turning occasionally until golden brown and crispy, or until baked to a nice golden color with thoroughly cooked meat, checking internal temperature at 160°F.

Remove the crispy Lebanese Arayes and allow them to rest for a minute. Slice each pita half in two, revealing juicy meat inside. Arrange on a platter and serve warm.
