Position a rack in the center of the oven and heat the oven to 400 degrees F.
Split each pita into two rounds. Lightly brush each round on both sides with olive oil and sprinkle with salt. Cut each round into 8 wedges and arrange in a single layer on rimmed baking sheets. Bake until golden and crisp, about 12 minutes.
Serve warm or at room temperature.
The chips can be made up to 2 days ahead and stored in an air-tight container. Re-crisp just before serving in a 250 degrees F oven for about 8 minutes.
