First,make up the tzatziki sauce by mixing all the ingredients in a small bowl. Cover and keep refrigerated.
Now add all the chicken filling ingredients to the pot and mix together. Put the lid on the pot and set on high pressure for 25 minutes.
When the time is up, leave it under pressure for a further 15 minutes and then do a quick release if necessary.
Remove the lid and drain off most of the liquid. Shred the chicken using 2 forks.
Now build the gyro with whichever ingredients you prefer topped with the tzatziki sauce.
