Lightly brush both sides of pita rounds with olive oil. Sprinkle one side with the Parmesan garlic seasoning mixture. Use a pizza cutter or sharp knife to cut each round into 8 wedges. Place wedges on an ungreased, rimmed baking sheet and bake for 6 to 7 minutes, until golden brown.
Remove from oven and allow to cool on baking sheet for about 5 minutes. Pita Chips will continue to crisp slightly after removed from the oven. Serve while still slightly warm.
