For the dressing: Make the dressing in a small bowl by whisking together the balsamic vinegar, garlic and oregano. While whisking, drizzle in the olive oil. Season with salt and pepper.
For the salad: Place the romaine lettuce in a bowl. Drizzle over the dressing and toss. Arrange on a platter to make a base for the salad. Artfully place the meats, peppers, tomatoes, artichoke hearts, olives and mozzarella balls around the platter. Garnish with the basil leaves and drizzle with the balsamic glaze.
