Combine the ingredients for the marinade with a pinch of salt and some freshly ground black pepper. Add the chicken thighs and mix to ensure they’re coated. Leave for at least 20 mins or overnight. Before you start cooking, combine the tzatziki ingredients and set aside.

Cook the chips following pack instructions in your air fryer (around 200C for 15-20 mins, giving them a shake every 5 mins). If you have two drawers then you can cook the chicken at the same time. If you’re using a single drawer air fryer, set the cooked chips aside, then add the chicken and cook at 180C for 20-25 mins, turning halfway through. Remove the chicken from the air fryer and leave to rest for 5 mins. Meanwhile, reheat the chips at 200C for 5 mins.

Slice the chicken, then top each flatbread with the tzatziki, tomato, red onion, chicken and chips. To serve, roll up the gyros and wrap in baking parchment, if you like.
