In a food processor or blender add chickpeas, tahini, garlic, lemon juice, salt, oil, and water. Blend on high until smooth. Remove from blender and set aside.
In a large bowl lets make the salad. Mix together chickpeas, tomatoes, cucumbers, red onion, parsley, garlic, zaatar, sumac, salt, lemon juice, and olive oil.
On a large plate, spoon a large dollop of hummus onto a plate and using the back of the spoon smear to the edges. Top with chickpea salad and serve with fresh pita bread!
