Prepare the golden crispies by mixing panko, garlic powder, and salt in a bowl. Heat olive oil in a pan over medium heat and add the panko mixture. Stir until golden brown and crispy.

Thinly slice the red onion using a mandoline.

In a large mixing bowl, combine the romaine lettuce, salami, provolone, red onion, and pepperoncini.

Add the golden crispies and Parmesan to the salad mixture.

For the dressing, mix olive oil, pepperoncini brine, and Italian seasoning in a small bowl. Pour over the salad and toss well.
