**Prepare the Butter Mixture**
In a small bowl, mix softened butter with garlic powder and Italian seasoning. Spread the mixture on one side of each bread slice.
**Assemble the Sandwich**
- Place one slice of bread, buttered side down, on a clean surface.
- Layer with shredded mozzarella cheese, crispy chicken slices, marinara sauce, and Parmesan cheese.
- Top with another slice of bread, buttered side up. Repeat for the second sandwich.
**Cook the Sandwiches**
Heat a skillet or griddle over medium-low heat. Place the sandwiches in the skillet and cook for 3-4 minutes per side, pressing gently with a spatula, until golden brown and the cheese is melted.
**Serve**
Remove from the skillet, let cool slightly, then slice and serve hot. Enjoy with extra marinara sauce for dipping!
