Preheat oven to 350 degrees.
Toast pitas 5 to 10 minutes in the preheated oven until crisp and break into bite size pieces (or omit the toasting like I did).
Place the pita, lettuce, green onion, cucumbers, tomatoes, mint and parsley in a bowl together and toss.
In a blender (I used my magic bullet), combine the garlic, sumac, lemon juice, olive oil, salt and pepper and blend until smooth and creamy.
Pour the dressing over the salad (I always like to start with a small amount then add more), add the feta and toss to combine.
