From an old Bon Appetit...and posted for ZWT #6. This makes a delicious summer lunch or light dinner. As an alternative eat it as a salad instead of stuffing the pitas. Serve with: Romaine salad and bowls of mixed green and black olives.
To make the vinaigrette, whisk together olive oil, white wine vinegar, and spices in medium bowl. Place drained garbanzo beans in large bowl and mix in enough vinaigrette to coat. Let stand 20 minutes or up to several hours to allow flavors to blend.
Add tomatoes, cucumbers, feta cheese, red onion, and parsley to garbanzo beans. Mix in additional vinaigrette to coat. Season bean salad to taste with salt and pepper. Fill pita halves with bean salad and top with dollop of yogurt. Place 2 pita halves on each of 4 plates; pass remaining vinaigrette separately.
