First, heat oven to 375°F. In a large, oven-safe heavy pot such as a Dutch oven, heat olive oil in the bottom of the pan over medium-high heat.
Add onions and cook for five minutes, until they begin to soften. Add garlic and saute for 5 minutes, until everything is wilted.
Add cumin, coriander, paprika, cayenne and salt, and cook for one minute. Add canned chickpeas and 1.5 cups broth. Bring mixture to a boil and boil for one full minute. P
Place a lid on the pot and transfer it carefully to the oven.
Bake chickpeas for 25 minutes.
Dice your tomatoes, cucumbers, and onion and toss with 1 teaspoon olive oil, salt, pepper and lemon juice to taste.
Make your yogurt / tahini sauce by combining 1 cup yogurt, ¼ cup tahini, 1 clove garlic, salt, pepper and lemon juice to taste — thin out the sauce with 1-3 tbsp water as neededn.
Meanwhile, bake your pita chips: Cut the pitas into chip-size wedges. Arrange on a large baking sheet and spray with olive oil cooking spray, sprinkle with salt.
Bake at 375 degrees for 10 minutes or until crispy and golden brown.
Assemble! Top the pita chips (use pita chips made from ½ of a whole wheat pita) with 1/8 of the chickpea mixture, ½ to 1 cup of the tomato mixture and a few tablespoons of the yogurt sauce.
