Cook bacon in a cast iron or non-stick skillet until crisp. Drain on paper towels.
Lightly wipe out skillet with a paper towel (ok to leave a little bacon love behind!) and butter one side of each slice of bread.
Place bread butter-side down on work surface. Top with bacon, shredded cheese and pickle slices. Top with second slice of bread, butter-side facing up.
Cook in the same pan as the bacon over medium heat, flipping every couple minutes until bread is lightly toasted and cheese is melted.
