Preheat oven to 400°.
Place pitas in a single layer on a baking sheet. Bake at 400° for 6 minutes or until toasted; break into bite-size pieces. Combine pita, sumac, and oil, tossing well to coat. Add lettuce and remaining ingredients; toss well.
Note: Ground sumac is available at Middle Eastern markets.
Good, takes a while to prep and it makes alot. I am not a huge parsley fan, but my partner liked this alot.
