Step 1: Marinate the Chicken

1. In a bowl, whisk together olive oil, ranch dressing, Worcestershire sauce, vinegar, lemon juice, minced garlic, and black pepper.
2. Place the chicken breasts in a resealable plastic bag or shallow dish and pour the marinade over them.
3. Seal or cover and refrigerate for at least 2-3 hours, preferably overnight for maximum flavor.

Step 2: Prepare the Parmesan Crust

1. In a small bowl, mix panko breadcrumbs, garlic salt, shredded Parmesan cheese, and melted butter.
2. Stir until the breadcrumbs are evenly coated and set aside.

Step 3: Cook the Chicken

1. Preheat your grill or a grill pan over medium-high heat.
2. Remove the chicken from the marinade and discard any excess liquid.
3. Grill the chicken breasts for 6-7 minutes per side, or until the internal temperature reaches 165°F (74°C).
4. Transfer the cooked chicken to a baking sheet.

Step 4: Assemble and Broil

1. Preheat your oven’s broiler.
2. In a small bowl, mix grated Parmesan cheese and ranch dressing to form a spread.
3. Spread a layer of the Parmesan-ranch mixture over each chicken breast.
4. Top each piece with a slice of provolone cheese.
5. Sprinkle the panko Parmesan mixture evenly over the provolone.
6. Place the baking sheet under the broiler for 2-3 minutes, or until the cheese is melted and the breadcrumb topping is golden brown.

Step 5: Serve

1. Remove from the oven and garnish with chopped fresh parsley, if desired.
2. Serve hot with sides like mashed potatoes, roasted vegetables, or a fresh salad.
