Step 1: Prepare the Chicken Marinade

1. In a mixing bowl, combine olive oil, lemon juice, garlic powder, onion powder, paprika, salt, and black pepper.
2. Place the chicken breasts in a ziplock bag or shallow dish and pour the marinade over them.
3. Let the chicken marinate for at least 30 minutes (for best results, marinate for 2-4 hours in the refrigerator).

Step 2: Grill the Chicken

1. Preheat your grill or grill pan to medium-high heat.
2. Remove the chicken from the marinade and place it on the grill.
3. Cook for 5-6 minutes on each side, until the internal temperature reaches 165°F (74°C).
4. Transfer the grilled chicken to a baking sheet lined with foil.

Step 3: Prepare the Parmesan Crust

1. In a bowl, mix the grated Parmesan, shredded Provolone, panko breadcrumbs, melted butter, mayonnaise, Italian seasoning, and garlic powder.
2. Stir until the ingredients are well combined and form a thick paste.

Step 4: Add the Parmesan Crust to the Chicken

1. Spread the Parmesan crust mixture evenly over each grilled chicken breast.
2. Press down gently to help it adhere.
