Method
Prepare chicken and produce
- Shred cooked chicken and pat it dry with paper towels; place in a large mixing bowl while still slightly warm.
- Finely chop pickles, pepperoncini, celery, and mince red onion so pieces are small and evenly distributed.
Make the dressing
- Whisk together red vinegar, Dijon mustard, dried oregano, sugar, salt, and pepper in a small bowl; slowly whisk in the olive oil until emulsified, then stir in the mayonnaise to stabilize.
Toss and rest
- Pour the dressing over the warm shredded chicken, add the chopped vegetables and grated Parmesan, and fold gently until well coated; taste and adjust seasoning, then refrigerate for at least 20 minutes to let flavors meld.
Assemble sandwiches
- Lightly toast the split rolls if desired, layer with arugula or romaine, add a generous scoop of the chicken salad, top with provolone or mozzarella if using, and finish with extra pepperoncini slices before serving.
Storage
- Store leftover chicken salad in an airtight container in the refrigerator for up to 3 days; keep rolls separate and assemble just before serving to prevent sogginess.
Notes
Use warm shredded chicken so the dressing absorbs flavor; 2 tablespoons mayonnaise stabilizes the vinaigrette and prevents soggy rolls. Store the salad up to 3 days refrigerated and keep bread separate for make-ahead lunches. Rotisserie chicken is a quick shortcut.
