Soak dried chickpeas in an ample amount of water at room temperature for 24 hours (or 3 hours if short on time).
Heat oven to 375°F (190°C). In a large pot, heat olive oil over medium-high heat. Add onions and cook for 5 minutes until softened.
Add garlic and sauté for 3 to 4 minutes more. Add spices, zest, and salt, cooking for one minute.
Add drained soaked or canned chickpeas and the appropriate amount of broth. Bring to a boil and boil for one minute.
Cover the pot and transfer it to the oven. Bake for the appropriate time based on the type of chickpeas used.
While the chickpeas bake, prepare the fixings: make pita chips, toast pine nuts, and prepare the tomato-cucumber salad and lemon-tahini yogurt.
Serve by layering pita chips, baked chickpeas, yogurt sauce, salad, parsley, and pine nuts.
