In a small bowl, combine softened unsalted butter with freshly minced garlic and optional chopped parsley. Mix until well blended and set aside.

Take your choice of bread and generously spread the garlic butter on one side of each slice. Lay them aside with the buttered sides facing up.

On the unbuttered side of your bread slices, layer the cheese starting with shredded mozzarella, followed by sharp cheddar and provolone. Place the other slice on top, buttered side facing out.

Preheat a non-stick skillet over medium-low heat. Place the assembled sandwiches in the pan, buttered side down.

Cook the sandwiches for about 3-4 minutes, or until the bottom is golden and crispy. Flip when ready.

Gently flip each sandwich to grill the other side and cook for another 3-4 minutes until golden brown and melted.

Remove the sandwiches from the skillet, slice diagonally, and serve immediately.
