Step 1

Spread 1/2" tablespoon of butter on each slice of bread, making sure to go all the way to the edges.

Step 2

Place the bread, butter side down, and lay two slices of the mozzarella on the bottom.

Step 3

Top the mozzarella with one tablespoon of Parmesan cheese, then the sun-dried tomatoes, dividing them evenly over both sandwiches.

Step 4

Add a small handful of arugula on top of the tomatoes, followed by two slices of bacon on each sandwich.

Step 5

Sprinkle the remaining Parmesan cheese on top of the bacon followed by two more slices of mozzarella.

Step 6

Place a 12" skillet on the stove over medium heat.

Step 7

When the pan is hot, carefully lay both sandwiches in the pan.

Step 8

If desired, you can press the sandwich, but this is completely optional. ** see note below

Step 9

Cook for two minutes and then rotate the sandwiches (don't flip them yet). Rotating them just helps them evenly brown. Grill for another two minutes or until the bottom is browned.

Step 10

Carefully flip the sandwich over and grill for an additional 3 to 4 minutes or until the cheese is thoroughly melted and the bottom side is nicely browned.

Step 11

Serve immediately!
