Preheat your oven to 350°F / 175°C and line a baking sheet with parchment paper.
Cut each pita pocket in half, then cut each half into 3 wedges for a total of 12 wedges.
Brush both sides of each pita wedge lightly with olive oil.
Arrange the wedges in a single layer on the baking sheet.
Bake for 8–10 minutes, flipping once halfway through, until golden brown and crispy.
While the chips bake, combine the plain yogurt, garlic salt, lemon juice, chopped red onion, and chopped parsley in a small bowl.
Season the yogurt mixture with salt and pepper to taste and stir well.
Remove the chips from the oven and let them cool for a minute to crisp up further.
Serve the warm pita chips alongside the cool yogurt dip.
Don't Overcrowd the Pan: For the crispiest chips, arrange them in a single layer with space in between. Overlapping causes them to steam instead of bake.
Season While Hot: For extra flavor, sprinkle spices like za'atar or sumac on the chips right after they come out of the oven. The heat helps the spices stick.
