Preheat griddle to about 375 degrees. Spread butter on one side of each slice of bread.

Cut bacon into small pieces ranging from the size of a dime to the size of a quarter. Cook on the griddle 5-7 minutes, until brown and starting to crisp. Remove from pan and place on a paper towel. Quickly rinse some of the bacon grease out of the griddle and return to heat.

Place 2 pieces of bread butter side down on the griddle. Lay 2 pieces of cheese on top. Divide the bacon crumbles in half and place on the cheese. Add 2 more slices of cheese, then other slice of bread, butter side up. Cook for 3-4 minutes, until lightly golden. Flip and cook on the opposite side until golden.

Remove from heat, slice in half and enjoy!
