Creating Greek Nachos is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare Pita Chips: Cut the pita breads into triangles. Arrange them in a single layer on a baking sheet.
3. Add Olive Oil: Drizzle the pita triangles with olive oil, then sprinkle with salt and pepper. Toss to coat evenly.
4. Bake Pita Chips: Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until golden and crispy.
5. Prepare the Toppings: While the chips are baking, assemble the toppings. In a bowl, combine cherry tomatoes, cucumber, red onion, olives, and parsley.
6. Make the Dressing: In another small bowl, whisk together olive oil, red wine vinegar, oregano, salt, and pepper.
7. Assemble the Nachos: Once the pita chips are baked, remove them from the oven. Layer the mozzarella and feta cheese evenly over the chips.
8. Add Toppings: Spoon the vegetable mixture over the cheese layer.
9. Final Bake: Return the baking sheet to the oven for an additional 5-7 minutes, allowing the cheese to melt slightly.
10. Drizzle Dressing: When done, remove from the oven and drizzle the dressing over the nachos.
