Creating your Vodka Sauce Chicken Parmesan Sandwich is simple if you follow these steps carefully.

1. Prepare Chicken: Season both sides of the chicken breasts with salt, pepper, and Italian seasoning.
2. Cook Chicken: In a large skillet, heat the olive oil over medium heat. Add the chicken breasts and cook for about 6-7 minutes on each side, until golden brown and cooked through.
3. Add Vodka Sauce: Once the chicken is cooked, pour the vodka sauce over it. Let it simmer for 5 minutes to allow the flavors to meld together.
4. Melt Cheese: Sprinkle the mozzarella and Parmesan cheese over the chicken. Cover the skillet and let cook for another 3-5 minutes, or until the cheese is melted and bubbly.
5. Prepare Bread: While the chicken is cooking, toast your bread slices until golden brown.
6. Assemble Sandwich: Place one chicken breast on each slice of toasted bread. Spoon extra vodka sauce over the top if you prefer.
7. Garnish: Add fresh basil leaves if desired for an aromatic touch.
8. Top with Bread: Close the sandwich with another slice of toasted bread and gently press down.
9. Final Toasting: For added crunch, you can toast the assembled sandwich in the skillet for an additional 1-2 minutes on each side.
10. Serve: Cut the sandwich in half, serve hot, and enjoy!
