Preheat your oven to 400°F (200°C).
Arrange the sliced eggplants on a baking sheet, brush with 1 tablespoon of olive oil, and season with salt and pepper. Roast for 25 minutes until tender.
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the pita squares and cook until crispy and golden. Remove and set aside.
In a bowl, mix the yogurt and minced garlic. Add salt to taste.
Layer the roasted eggplants in a serving dish. Top with crispy pita pieces, then spread the yogurt mixture over the top.
Heat the remaining tablespoon of olive oil in a small pan and toast the pine nuts until golden. Sprinkle over the yogurt layer.
Garnish with chopped parsley and serve warm or at room temperature.
