Preheat the oven to 375°F (190°C).
Place pita rounds on a cutting board and, if whole, gently separate the layers; brush or drizzle about 1 teaspoon of olive oil over one side of each pita.
Sprinkle the oiled side of each pita with salt and freshly ground black pepper.
Cut each pita into 8 triangles using a sharp knife.
Arrange the pita triangles in a single layer on a parchment-lined or nonstick baking sheet, making sure pieces do not touch.
Bake for 10 minutes, or until the chips are crisp and lightly golden.
Remove from the oven and let the chips cool completely on the baking sheet before serving or storing.
