Step 1

Combine the yogurt, mayonnaise, chives, parsley, and garlic in a small bowl. Season with salt and pepper as needed; set aside.

Step 2

Heat the oil in a large skillet over medium heat until shimmering. Add the chicken, season with salt and pepper, and sauté until cooked through, 5 to 7 minutes. Remove from the heat and toss with 2 tablespoons of the ranch dressing.

Step 3

Lay 1 lettuce leaf and 2 slices of tomato on one half of each pita. Evenly divide the chicken among the 4 pitas. Drizzle with more ranch dressing, fold in half, and serve. These sandwiches are best made and eaten immediately.
