In a mixing bowl, combine 40g plain flour, 40g 0-5% Greek Yogurt, and a pinch of salt. Mix until a dough forms.

Knead the dough for a minute on a floured surface until a smooth ball, then set aside to rest.

In a small bowl, mix together the Greek yogurt, minced garlic, grated cucumber, a pinch of salt and pepper and olive oil until well combined. Set aside.

Slice your chicken breast into chunks and season with a pinch of oregano, paprika and salt.

Heat an oiled frying pan over medium heat. Add the chicken and cook until golden and cooked through, turning as needed.

On a floured surface, roll out the flatbread dough (using a rolling pin) to your desired thickness. Cook in a dry skillet / frying pan over medium heat for about 2 minutes per side, or until golden and puffed up.

Assemble the flatbread by spreading the tzatziki sauce on top, then adding the chicken, kalamata olives, sliced cucumber, cherry tomatoes and red onion.
