Preheat the oven to 400 degrees Split the pitas open into 8 halves. Lay the bread out on your countertop, insides facing up. In a small bowl, mix together the paprika, thyme, oregano and cinnamon. Sprinkle the spices evenly over the split bread. Place the bread on an oven rack and toast until golden and crisp, about 4 to 5 minutes. Remove from the oven and tear into jagged pieces about the size of tortilla chips and reserve.
On a large serving platter, combine the tomatoes, half of the cucumber, and the onion, celery, bell pepper and parsley; season with salt and pepper.
To a food processor, add the remaining cucumber, the yogurt, cumin, garlic, lemon juice and Tabasco sauce and a little salt. Process the ingredients, adding the EVOO in a thin stream until smooth; taste the dressing and adjust the seasonings.
Arrange the pita crisps on the salad, then drizzle the dressing all over. Finish off your salad with a pile of the feta, pepperoncini and olives. Serve with the stuffed grape leaves on the side. Opa! (I think thats Greek for Yum-O!)
