Heat a skillet over low heat and add 1 teaspoon of butter. Once melted, place a slice of bread in the skillet.

While the bread is toasting, place the bacon next to the bread in the skillet to cook.

Keep moving the bread to prevent the butter from burning. Once golden brown, flip the bread and add another teaspoon of butter.

Place the bacon on one slice of bread, cover with cheese shreds, and top with the other slice of bread (the side that was heated first should face the cheese to melt it quickly).

Add the remaining butter and keep flipping the entire sandwich until both sides are golden brown. Then it's ready to serve.
