In a large bowl, combine the chopped Romaine lettuce, diced cucumber, sliced radishes, diced tomatoes, diced bell pepper, chopped parsley, chopped mint leaves, and sliced green onions.
If using, gently fold in the pomegranate seeds for added sweetness and color.
Just before serving, add the toasted pita bread pieces to the salad.
In a small bowl, whisk together the extra virgin olive oil, fresh lemon juice, minced garlic, ground sumac, Dijon mustard, salt, and black pepper until well combined.
Pour the dressing over the salad and toss gently to coat all the ingredients evenly.
Enjoy your meal!
