Heat a frying pan to medium heat. Then, generously spray pan with cooking spray.
Butter each slice of your bread on the side that will be on the frying pan. Place both pieces next to each other in the pan.
Put 1 slice of pepper jack cheese on one slice of bread. Place a slice of aged gouda on the other slice of bread.
Next, spread mayo on one slice of cheese. Whichever slice that is, put the shredded cheese on that slice. It will act as a glue for the shredded cheese to keep it from getting all over the place.
Sprinkle some Italian seasoning on top of the shredded cheese.
Put the slices of bread together. By now, the cheese will have started to melt and will help keep the sandwich together naturally.
Lastly, flip once or twice so both sides of the bread are a beautiful golden brown. If you need to turn down the heat to a medium-low so the bread doesn’t burn, please do.
Heat up your favorite soup and enjoy!
