Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
Brush the olive oil over the pita breads and sprinkle them with salt, pepper, and sumac.
Bake for 10 minutes, flipping halfway through.
Once cool enough to handle, tear or cut the pita into bite-sized pieces (“croutons”).
For the salad
Whisk together the olive oil, lemon juice, pomegranate molasses, garlic, sumac, and cumin. Taste and season with salt and pepper as desired.
In a large salad bowl, toss together the lettuce, cucumber, tomatoes, green onions, radishes, parsley, mint, and pita croutons.
Pour the dressing over the salad and toss to coat the ingredients.
Notes
Once assembled, this salad is best enjoyed immediately. If you have any leftovers, store them in an airtight container in the refrigerator for up to a day.
