Whisk all vinaigrette ingredients together vigorously until fully emulsified. Taste boldly and adjust until punchy, tangy, and deeply savory.
Cook pasta in heavily salted water until just al dente. Reserve ¼ cup pasta water before draining.
Drain and rinse pasta thoroughly under cold water. Shake well and allow to air dry briefly.
Dress the pasta with half the vinaigrette immediately and toss to coat before adding any other ingredients.
Add salami, pepperoni, cherry tomatoes, bell peppers, cucumber, olives, sun-dried tomatoes, pepperoncini, and red onion. Toss thoroughly and confidently.
Pour remaining vinaigrette over the salad. Toss again until everything is generously coated.
Fold in mozzarella, parmesan, basil, and parsley gently to keep the mozzarella intact.
Taste and adjust with salt, pepper, and red wine vinegar until bold and well seasoned.
Cover tightly and refrigerate for at least 1 hour. Overnight is strongly recommended.
Before serving, stir well and taste again. Refresh with olive oil, red wine vinegar, salt, and fresh basil. Serve cold.
