This light and DELICIOUS recipe is courtesy of Pamela Salzman's book Kitchen Matters. Full of great recipes like this one so I highly recommend you pick it up!
Scatter half of the cucumber, tomatoes, feta, and olives on top. make sure every chip has something on it.
Dollop half of the hummus and tzatziki all over the pita chips and vegetables.
Layer the remaining pita chips on top and repeat with the remaining toppings.
Notes
I made pita chips for this recipe by splitting pita bread with a knife, brushing each side with olive oil and baking at 35oF on a baking sheet for about 20 minutes.
