Preheat your oven to 190 degrees and line two baking trays with baking paper before setting them aside.
Pour the oil into a small container and have your pastry brush and sea salt flakes close by.
Cut the pita bread in half and then again so that you have 8 even pieces. Repeat until all of your pita bread has been cut.
Arrange the pita bread pieces on your baking trays, ensuring they are not on top of each other to help them cook evenly.
Use your pastry brush to lightly coat the pita bread pieces with oil, before sprinkling them with the sea salt flakes.
Place the trays in your preheated oven and cook for 5 minutes or until the pita bread begins to brown.
Remove the trays from the oven and allow the pita bread chips to cool for 5 minutes before transferring to a wire rack to cool completely.
