Step 1: Preheat the oven
Preheat your oven to 400°F (200°C) so it is fully heated and ready for roasting. A hot oven helps the chicken cook evenly and gives the vegetables better color.

Step 2:

Step 3: Season the chicken
Place the chicken breasts in a bowl and toss with olive oil, salt, pepper, garlic powder, and paprika until evenly coated on all sides.

Step 4:

Step 5: Arrange on the pan
Spread the seasoned chicken and mixed vegetables on a sheet pan in a single layer. Keep the vegetables in even-sized pieces so everything roasts evenly.

Step 6:

Step 7: Roast the chicken and vegetables
Bake for 20 to 25 minutes until the chicken is cooked through and the vegetables are tender with lightly browned edges.

Step 8:

Step 9: Make the herby ranch
While the chicken bakes, stir together Greek yogurt, ranch seasoning mix, and fresh herbs in a bowl until smooth and creamy.

Step 10:

Step 11: Warm the pitas
Place the pitas in the oven during the last 5 minutes of cooking so they warm through and become soft and flexible.

Step 12:

Step 13: Rest and slice the chicken
Let the chicken rest for 3 to 5 minutes after baking, then slice into strips or bite-sized pieces to keep it juicy.

Step 14:

Step 15: Assemble and serve
Fill each warm pita with sliced chicken and roasted vegetables, then drizzle with the herby ranch and serve right away.
