Creating a Turkey Melt is straightforward if you follow these simple steps:

1. Prep the Bread: Spread mayonnaise on one side of each slice of bread. If using, spread Dijon mustard on the other side.
2. Assemble the Sandwich: Lay one slice of bread mayo-side down on a clean surface. Layer on the turkey, cheese, and any additional toppings like spinach or tomato. Top with the second slice of bread, mayo-side up.
3. Heat the Pan: In a skillet, melt half of the butter over medium heat.
4. Cook the Sandwich: Place the sandwich in the skillet and cook until golden brown, about 3-4 minutes. Press down gently with a spatula for even browning.
5. Flip: Carefully flip the sandwich and cook the other side, adding the remaining butter to the skillet if needed. Cook for another 3-4 minutes until the cheese is melted and both sides are golden brown.
6. Check for Doneness: The sandwich is ready when the cheese is melted and the bread is nicely toasted.
7. Slice and Serve: Remove from the pan and let it cool for a minute. Slice the sandwich in half and enjoy!
