In a large bowl, combine the chicken, Greek yoghurt, lemon juice, olive oil, garlic, paprika, cumin, coriander, cinnamon, salt and pepper. Mix well until every piece of chicken is evenly coated.
Transfer the chicken to your air fryer basket and cook at 190°C (375°F) for 15–16 minutes, shaking halfway through, until cooked through and lightly golden. Leave to rest for a few minutes before slicing.
Cut the pita bread into bite-sized pieces. Drizzle with a little olive oil and season with paprika, garlic powder and a pinch of salt. Air fry for 3–5 minutes at 190°C until golden and crispy.
Meanwhile, chop the lettuce, quarter the tomatoes, chop the cucumber, slice the spring onions and radishes, and finely chop the mint. Add everything to a large serving bowl.
Whisk together the olive oil, lemon juice, garlic, sumac, pomegranate molasses (or balsamic vinegar), salt and pepper. Pour over the salad and toss well.
Top the dressed salad with the sliced chicken and scatter over the crispy pita croutons. Serve immediately while the croutons are still crunchy.
