In a large, deep glass bowl, combine the lettuce (or arugula), cucumber, tomato, bell pepper, red onion, and cilantro. Toss the ingredients gently to mix.
In a small bowl, whisk together the lemon juice, olive oil, pomegranate molasses, salt, black pepper, and dried mint until the dressing is well combined.
Add the fresh pomegranate seeds to the bowl of vegetables, then pour the dressing over the salad.
Gently toss the salad again until all the ingredients are coated with the dressing.
Garnish the salad with some fresh mint leaves or an extra sprinkle of pomegranate seeds.
Serve the pomegranate vegetable salad immediately while fresh.
