Lay one slice of bread flat and layer with ham slices and pineapple. Sprinkle about ½ cup of shredded mozzarella over the pineapple, then add a pinch of dried oregano for extra flavor.

Place the second slice of bread on top to complete the sandwich. Generously sprinkle the remaining mozzarella cheese over the top slice of bread - this will create the crispy cheese crust.

Melt butter in a nonstick skillet or cast iron pan over medium-high heat. Make sure the butter coats the entire bottom of the pan evenly.

Carefully place the sandwich in the hot skillet with the cheese-topped side facing up. Cook for 3-5 minutes until the bottom slice turns golden brown and crispy.

Using a spatula, carefully flip the sandwich so the cheese side is now down against the hot pan. Cook for another 3-5 minutes until the cheese forms a golden, crispy crust and the inside cheese is completely melted.

Remove from heat and let cool for just 30 seconds before cutting. Slice diagonally and serve right away while the cheese is still gooey inside and crispy outside.
