To create your Crispy Chicken Caesar Sandwich, follow these simple steps:

1. Marinate Chicken: In a bowl, combine buttermilk and chicken breasts. Allow to marinate for at least 30 minutes in the refrigerator.
2. Prepare Coating Station: Set up three bowls: one for flour mixed with salt and pepper, another for beaten eggs, and the last for panko breadcrumbs mixed with garlic powder, onion powder, and Italian seasoning.
3. Coat Chicken: Remove the chicken from the buttermilk, allowing excess to drip off. Dredge each piece in flour, dip into the egg wash, and finally coat thoroughly in the panko breadcrumb mixture.
4. Heat Oil: In a large frying pan, heat olive oil over medium heat until hot but not smoking.
5. Fry Chicken: Fry the coated chicken breasts for about 5-7 minutes per side, or until golden brown and cooked through. A meat thermometer should read 165°F (74°C).
6. Toast Bread: While the chicken is frying, toast your bread slices until golden and crispy.
7. Assemble Sandwich: Spread Caesar dressing generously on one side of each slice of toasted bread. On one slice, layer the crispy chicken followed by romaine lettuce and additional parmesan.
8. Top and Serve: Place the second slice of toast on top, dressing side down, and press gently. Cut the sandwich in half and garnish with extra parmesan if desired.
