Set your Gourmia sous vide cooker to 167° and when it comes to temperature carefully place 5 eggs into the water bath.
Cook for 13 minutes and transfer to a bowl of ice water.
For the hollandaise whisk 3 egg yolks and combine with milk and lemon juice in a pan over medium heat slowly adding 8 tablespoons of melted butter. Whisk until thickened.
Crack each egg shell over a slotted spoon, which will drain off any loose egg white leaving you with perfectly poached eggs.
Top each pita with sliced tomatoes, onions, feta cheese, gyro meat, a poached egg and hollandaise sauce.
