Making Sheet Pan Chicken Pitas with Herby Ranch is simple if you follow these straightforward steps:

1. Preheat the Oven: Set your oven to 400°F (200°C).
2. Prepare the Chicken: In a bowl, combine olive oil, garlic powder, smoked paprika, dried oregano, salt, and black pepper. Add the chicken breasts to the bowl and toss until fully coated.
3. Prepare Vegetables: On a large sheet pan, spread the sliced bell peppers and onions in an even layer. Drizzle a bit more olive oil and a pinch of salt over the vegetables.
4. Add Chicken to Pan: Arrange the seasoned chicken breasts on top of the vegetables on the sheet pan.
5. Bake: Place the sheet pan in the preheated oven and bake for about 20-25 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
6. Prepare Herby Ranch Dressing: While the chicken is baking, mix Greek yogurt, mayonnaise, chopped dill, chopped chives, and lemon juice in a bowl. Stir well to combine, and set aside.
7. Warm Pitas: When the chicken is nearly done, warm the whole wheat pitas in the oven for the last 5 minutes.
8. Assemble: Remove the sheet pan from the oven. Slice the chicken into strips and place them inside each warm pita alongside the roasted vegetables.
9. Drizzle Dressing: Generously drizzle the herby ranch dressing inside each pita.
10. Garnish and Serve: Top with a slice of lettuce if desired, and serve immediately.
