In a small mixing bowl, whisk together Greek yogurt, olive oil, red wine vinegar, pepperoncini brine, Dijon mustard, minced garlic, oregano, red pepper flakes and salt until smooth.

In a large mixing bowl, combine garbanzo beans, white beans, diced turkey, diced salami, chopped bell pepper, halved cherry tomatoes, sliced pepperoncini, red onion, parsley, and provolone or mozzarella. Gently toss until mixed.

Pour the dressing over the salad ingredients and toss to ensure all are coated.

Cover the salad and refrigerate for at least 30 minutes to allow flavors to meld before serving.
