Begin by rinsing and drying your romaine lettuce thoroughly. Chop the lettuce into bite-sized pieces, along with the salami and mozzarella.

In a large mixing bowl, combine the chopped romaine, salami, mozzarella, and chickpeas. Gently toss these ingredients together.

In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, oregano, salt, and pepper until well-emulsified.

Pour the freshly made dressing over the salad mixture and toss until everything is evenly coated.

Let the salad rest for about 5-10 minutes before serving to allow flavors to meld.
