01 - Bring a large pot of salted water to a boil. Cook the tortellini according to package directions until tender. Drain in a colander and rinse under cold running water to halt cooking and cool completely. Set aside.
02 - In a large mixing bowl, combine the cooled tortellini, halved cherry tomatoes, shredded lettuce, thinly sliced red onion, sliced pepperoncini, roasted red peppers, sliced cucumber, and cubed provolone cheese. Toss gently to distribute evenly.
03 - In a small bowl, whisk together the olive oil, red wine vinegar, minced garlic, dried oregano, dried basil, Dijon mustard, salt, and pepper until the mixture is fully emulsified and slightly thickened.
04 - Pour the prepared dressing over the salad mixture and toss gently, ensuring all ingredients are evenly coated without crushing the tortellini or vegetables.
05 - Transfer the dressed salad to a serving platter or bowl. Sprinkle grated Parmesan over the top and finish with several generous twists of freshly ground black pepper.
06 - Refrigerate for 15 minutes to allow the flavors to meld before serving, or serve immediately if preferred.
