Assemble the Salad
Place the chopped romaine and radicchio in a large salad bowl.
Layer the mozzarella, salami, chickpeas, black olives, yellow bell pepper, cucumber, sliced pepperoncini, grape tomatoes, and red onion on top of the lettuce.
Make the Dressing
In a medium bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, grated garlic, oregano, and crushed red pepper flakes.
Season the dressing with salt and black pepper to taste.
Toss the Salad
Pour the dressing over the salad and gently toss to combine.
Sprinkle the shaved Parmesan over the top before serving.
Notes
Vegetarian Option: Omit the salami for a vegetarian version.
Customizable Add-Ins: Add artichoke hearts, roasted red peppers, or croutons for extra flavor and texture.
Make Ahead: Prepare the salad ingredients and dressing separately up to 1 day in advance. Combine just before serving for the freshest taste.
