Making a Provolone Grilled Cheese Sandwich involves simple steps. Follow these guidelines to create your sandwich:

1. Prepare the Bread: Begin by laying out your slices of bread on a clean surface.
2. Butter the Bread: Spread a thin layer of butter on one side of each slice of bread. Ensure even coverage for toasting.
3. Layer the Cheese: On the unbuttered side of two slices, layer the provolone cheese generously.
4. Add Extras: If desired, place tomato slices and basil or spinach on top of the cheese. Season with optional salt and pepper.
5. Top and Close: Place the other slices of bread on top, buttered side facing out.
6. Heat the Pan: Preheat a skillet over medium heat.
7. Grill the Sandwich: Once the skillet is hot, place the sandwiches in the skillet. Grill until the bread is golden brown, about 2-4 minutes.
8. Flip and Continue Cooking: Carefully flip the sandwiches without spilling any filling. Cook for another 2-4 minutes until the opposite side is also golden and the cheese has melted.
9. Check for Doneness: If the cheese isn’t fully melted at this point, lower the heat slightly and cook for an additional minute or so, ensuring the bread doesn’t burn.
10. Serve: Once both sides are golden and the cheese is melty, remove the sandwiches from the skillet. Allow them to cool for a minute before slicing in half to serve.
