Pour olive oil into a skillet and warm it over medium heat. Add the finely chopped onion and sauté until soft and golden, about 3-4 minutes.

Stir in the minced garlic and cook for approximately 30 seconds until fragrant.

Add the ground beef with cumin, oregano, paprika, salt, and black pepper. Cook until fully browned.

In a bowl, whisk together Greek yogurt, lemon juice, garlic, olive oil, and salt until smooth.

Warm the pita breads in the microwave or skillet until pliable.

Fill each pita with the beef mixture, tomatoes, cucumber, and parsley.

Drizzle with lemon garlic yogurt sauce just before serving.
