How to Make the Best Grilled Cheese Ever

2 slices potato bread
1 slice swiss cheese
1 oz goat cheese, crumbled

Before getting started, make sure your cheese is out and ready, so that you can quickly place it on the bread when it's time. Place the bread in a small skillet and heat over medium-high heat for about 3-4 minutes, or until the side of the bread that's touching the pan is just starting to toast.
Turn the heat down to low and flip the bread, so the toasted side is up.
Moving quickly, place the cheese on one slice of bread, and top with the other piece of bread.
The first side of the sandwich will probably toast quickly (about 1 minute), since the pan is still warm from being at a higher temperature. Once it's toasted to your liking, flip to the other side. 
By now, you should see the cheese starting to melt. The second side of the sandwich will take a little longer to toast, about 2-3 minutes. This process is what gets the bread toasty (without butter), and also allows the cheese to melt fully.
