Italian Grinder Chopped Salad

Chop the romaine lettuce into 1/2-inch pieces and place them in a large salad bowl until you have about 6 cups of chopped lettuce.
Stack the provolone cheese, salami, and ham slices together, then roll them tightly and slice into 1/4-inch wide strips to create ribbon-like pieces. Add to the bowl with the lettuce.
Finely slice the red onion into thin half-moons, quarter the tomato, and slice the pepperoncini peppers into rings. Add these to the bowl along with the whole pitted kalamata olives.
In a small bowl, whisk together the olive oil, red wine vinegar, dried oregano, black pepper, and salt until well combined to create the dressing.
Pour the dressing over the salad ingredients and toss thoroughly with salad tongs until all components are evenly coated.
Add the mayonnaise and grated Parmesan cheese to the salad and toss again until the mayonnaise is distributed and creates a creamy coating on the ingredients.
Serve immediately in individual bowls, ensuring each portion gets a generous amount of the meat, cheese, and vegetable mixture.
