Step 1

Place the chicken in a large food bag with 3 tablespoons of oil, the yogurt, garlic, lemon juice, apple cider vinegar, oregano, salt, pepper, coriander, and onion powder. Seal the bag and use your hands to mix and massage the marinade into the chicken thoroughly. Leave in the fridge for at least 3 hours and up to 24 hours.

Step 2

Heat a tablespoon of olive oil in a large frying pan on a medium-high setting. Fry the chicken thighs for about 5 minutes on each side, until well browned and cooked through in the middle.

Step 3

Slice the chicken up into chunks.

Step 4

Fill the flatbreads with the chicken, tzatziki, and vegetables, and fold the sides up. You can secure them with some parchment paper or foil if desired.
