In a medium bowl, whisk together the mayonnaise, red wine vinegar, minced garlic, sweetener, Italian seasoning, a pinch of salt, and a sprinkle of red pepper chili flakes. Continue whisking until the mixture is smooth and creamy. Allow the dressing to sit for 5-10 minutes to let the flavors meld beautifully.

While the dressing is resting, slice the ham, salami, and pepperoni into ¼-inch pieces. Cut the provolone cheese into small cubes. Shred the iceberg lettuce to create a crunchy base.

In a large mixing bowl, combine the shredded iceberg lettuce, the sliced deli meats, cheese cubes, halved grape tomatoes, sliced pepperoncini peppers, and diced red onion. Gently toss these ingredients together.

Drizzle the creamy dressing over the salad ingredients. Toss the mixture until every piece is well-coated with the dressing.

Serve the salad immediately for maximum crunch, or store components separately in an airtight container.
