Mix the soft butter, parmesan cheese, garlic powder, and Italian seasoning in a bowl until smooth and well combined. This will be your flavor-packed spread.
02 -
Spread the garlic butter mixture evenly on one side of each bread slice. Place all slices on a sheet tray, butter side up, until you're ready to build your sandwiches.

Heat a skillet over medium-low heat. Place a slice of bread butter side DOWN in the skillet. Layer on a slice of mozzarella, 6 pepperoni slices, another slice of mozzarella, 6 more pepperonis, and a final slice of mozzarella.
04 -
Top with another slice of bread, butter side UP. Don't worry if you have some leftover pepperoni - snack on it while you cook!
05 -
Cover the skillet with a lid to help melt the cheese. Cook until the bottom bread is golden brown, about 3-5 minutes. The lid helps get that cheese all melty while the bread gets crispy.
06 -
Carefully flip the sandwich using a spatula. Place the lid back on and continue cooking until the other side is golden brown and the cheese is completely melted in the center.

Repeat the process with the remaining bread and fillings to make a total of 4 sandwiches. Serve immediately with warm pizza sauce for dipping.
