If using canned chickpeas, drain and rinse them. If using cooked chickpeas, ensure they are warm.
In a mixing bowl, combine the plain yogurt, minced garlic, tahini, and lemon juice. Mix until smooth and well combined. Season with salt to taste.
Preheat your oven to 350°F (175°C).
Place the torn pita bread pieces on a baking sheet and drizzle with 1 tablespoon of olive oil. Toss to coat the pieces evenly.
Toast in the preheated oven for about 10-15 minutes, or until they are golden brown and crispy.
In a small skillet, heat 1 tablespoon of olive oil over medium heat.
Add the pine nuts or slivered almonds and toast until they are golden brown, stirring frequently to prevent burning. Remove from heat and set aside.
In a serving dish or individual bowls, layer the crispy pita bread pieces.
Top with the warm chickpeas.
Pour the yogurt sauce over the chickpeas and pita, spreading it out evenly.
Drizzle with the remaining 1 tablespoon of olive oil.
Sprinkle the toasted nuts over the top.
Garnish with ground cumin, ground paprika (if using), chopped fresh parsley, pomegranate seeds, and sumac if desired.
Enjoy your meal!
