Preheat oven to 375°F (190°C).
Toss pita squares with 1 tablespoon olive oil and a pinch of salt on a baking sheet.
Bake pita for 8 to 10 minutes or until golden and crisp, then set aside to cool.
In a small bowl, whisk together the remaining olive oil, lemon juice, pomegranate molasses, minced garlic, sumac, and salt.
In a large mixing bowl, combine the lettuce, tomatoes, cucumbers, radishes, green onions, parsley, and mint.
Add the toasted pita to the vegetable mixture.
Pour the dressing over the salad, toss thoroughly to coat, and serve immediately to maintain bread crispness.
