Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
In a small bowl, mix together the olive oil, garlic powder, onion powder, smoked paprika, dried oregano, salt, and pepper to create a marinade.
Place the chicken breasts on the baking sheet and brush the marinade generously over both sides.
Scatter the cherry tomatoes, cucumber, and red bell pepper around the chicken on the baking sheet. Drizzle a little olive oil over the vegetables and season with salt and pepper.
Roast in the preheated oven for about 20-25 minutes, or until the chicken is cooked through (internal temperature of 165°F or 75°C) and the vegetables are tender.
While the chicken and vegetables are roasting, prepare the herb ranch slaw. In a bowl, whisk together the Greek yogurt, mayonnaise, lemon juice, dried dill, salt, and pepper.
Stir in the chopped fresh parsley to the dressing, then toss in any leftover vegetables you have for crunch and flavor.
Once the chicken is done, remove it from the oven and let it rest for a few minutes before slicing it into strips.
To assemble the pitas, place some of the sliced chicken inside each whole wheat pita, top with the roasted vegetables, and add a generous spoonful of herb ranch slaw.
Notes
Serve the filled pitas on a wooden board, garnished with extra parsley and lemon wedges on the side for a fresh touch. Enjoy!
