Add your beef to a bowl and add the salt and pepper and mix lightly combine.
Take a look at your buns and patty out burgers about 1/2 inch larger on all sides than your bun.Mine were about 2 1/2 to 3 inches across and about an inch thick.
Set the patties aside briefly while you toast the buns.
In a large skillet over medium high heat, melt half the butter and add the buns; cut side down and toast until golden brown--about 3-4 minutes or so. Set aside. It's okay to do batches if needed.
Add the remaining butter to the same pan and melt; add the burgers, leaving space around them and allow them to brown (do not press on them!) about 5-6 minutes per side, flipping once.
About three minutes or so before they are done, add enough cheese to cover the burgers and place a lid on the pan to melt the cheese.
Transfer the burgers to your toasted buns and add bacon and toppings of your choice. Use a toothpick to hold them together if needed. Serve warm.
