Prepare the Chicken: Start by seasoning your chicken breasts with montreal chicken seasoning, then drizzle with olive oil. Next dredge your chicken breasts in flour, ensuring each piece is well-coated. Next, dip the chicken into beaten eggs, allowing any excess to drip off. Finally, coat the chicken with panko breadcrumbs, pressing gently to ensure the breadcrumbs adhere well.

Cooking the Chicken: Heat your griddle to a medium-high setting. Place the breaded chicken on the griddle and cook for 5-7 minutes on each side. Be sure to flip the chicken halfway through to avoid burning and ensure even cooking. The goal is to achieve a golden, crispy exterior while the chicken remains juicy inside.

Adding the Marinara and Cheese: Once the chicken is cooked through, spoon marinara sauce over each piece. Sprinkle generously with shredded mozzarella cheese. Cover the chicken with a heat-resistant lid to melt the cheese.

Toasting the Croissants: While the cheese is melting, lightly toast your croissants on the griddle. This step adds a wonderful crunch and a hint of buttery flavor to your sandwich.

Assembling the Sandwich: Place the cheesy, marinara-topped chicken onto the bottom half of your toasted croissant. Add parmesan cheese to taste and fresh basil leaves. Top with the other half of the croissant and press down gently.
