Preheat your oven to 400°F (200°C) and prepare a baking sheet lined with parchment paper or lightly greased.

In a medium skillet, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add the diced chicken breasts and cook for about 5-7 minutes until browned and cooked through.

Stir in minced garlic, dried basil, oregano, thyme, salt, and pepper, cooking for an additional 1-2 minutes until fragrant.

Brush each pita with remaining olive oil and distribute the chicken mixture evenly over them.

Sprinkle mozzarella and Parmesan cheese over the chicken, then add cherry tomatoes, sliced red onion, and black olives.

Place pitas in the oven and bake for 10-12 minutes, until cheese is melted and bubbly.

Garnish with fresh basil leaves and drizzle with balsamic glaze before serving.
