Rinse and chop the romaine lettuce into bite-sized pieces and place it in a large bowl.
Thinly slice the red bell pepper and soak red onion slices in cold water for 10 minutes to mellow their flavor before adding them along with olives, pepperoncini, and artichokes.
Fold turkey slices and layer them in the bowl with provolone and capicola.
In a separate bowl, whisk together vinaigrette ingredients: apple cider vinegar, olive oil, oregano, garlic powder; season to taste with salt and pepper.
Pour the vinaigrette over the salad and toss gently to combine. Add fresh herbs before serving.
