Wash and dry the salad greens thoroughly. Tear or chop them into bite-sized pieces and place them in a large salad bowl.
Add the rest of the salad ingredients except for the Parmesan cheese into the bowl with the salad and mix.
In a small bowl, whisk together the extra-virgin olive oil, red wine vinegar, minced garlic, Dijon mustard, dried oregano, salt, and black pepper until well combined.
Drizzle the dressing over the salad and gently toss everything together until the ingredients are evenly coated with the dressing.
Sprinkle the grated Parmesan cheese over the top of the salad. This adds a burst of flavor and a touch of saltiness.
Divide the Italian Sub Salad among serving plates. It's ready to be enjoyed as a satisfying meal or a side dish. You can also serve it with some crusty Italian bread or garlic bread on the side for an extra treat.
