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

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare the Chicken: Cut the chicken breasts into bite-sized pieces. In a bowl, combine the chicken with olive oil, garlic powder, paprika, salt, and black pepper. Toss until the chicken is evenly coated.
3. Add Vegetables: Spread the seasoned chicken on the prepared baking sheet. Add the sliced bell peppers and red onion around the chicken.
4. Bake: Place the baking sheet in the oven and bake for 20 minutes or until the chicken is cooked through and the vegetables are tender.
5. Make the Dressing: While the chicken and veggies are baking, prepare the herby ranch dressing. In a bowl, mix together Greek yogurt, mayonnaise, apple cider vinegar, dill, garlic powder, onion powder, salt, and pepper. Stir until smooth.
6. Warm the Pita: During the last few minutes of baking, warm the pita breads in the oven for about 2-3 minutes until soft.
7. Assemble the Pitas: Once everything is cooked, take the baking sheet out of the oven. Place a handful of spinach or mixed greens in each pita, followed by the chicken and vegetable mixture.
8. Add Dressing: Drizzle the herby ranch dressing over the filling in each pita.
9. Serve: Enjoy your delicious Sheet Pan Chicken Pitas with Herby Ranch warm and fresh!
