For the crispy pita:
For the salad:
For the dressing:
Preheat oven to 350°F.
Toss pita with olive oil and salt and bake for 10 to 12 minutes. Stir pita, making sure to rotate outside edges to the middle and bake another 8 to 10 minutes until golden brown and crispy. Transfer to mixing bowl and toss with sumac. Set aside until ready to serve.
For the dressing smash a clove of garlic with the back of a knife and peel. Mince the garlic then add salt and use the back of your knife to mash garlic into a paste by pressing it against your cutting board in a dragging motion. In a small mixing bowl combine the garlic paste, lemon juice, red wine vinegar, cumin, and coriander. Add labneh, buttermilk, honey, and pomegranate syrup, and whisk until well incorporated.
In a large mixing bowl add the cherry tomatoes, cucumbers, red bell peppers, radishes, red onion, fresh pomegranate seeds, parsley, mint, dill, romaine, and dressing then toss to combine.
Divide evenly in shallow bowls and crumble pita chips on top. May garnish with additional pomegranate syrup and sumac if desired. Serve immediately.
