1Preheat oven to 350.
Whisk together olive oil and egg white in a small bowl, set aside.
Using scissors, cut the pitas in half. Open up the pockets, and cut each half into 2 half circles. Stack half circles 2 at a time, then cut into 3 wedges. You should end up with 12 "chips" from each whole pita.
2Using a pastry brush, lightly brush the inside of each pita chip with olive oil mixture. Place chips on a baking sheet, oil-side up, in a single layer. Sprinkle herb seasoining over each chip.Store chips in an airtight container or plastic bag.
3Bake for 15 minutes, or until golden brown and crispy. (If you bite into a chip and it's chewy, that means they're not done yet!)
