Add the hamburger patties and cook for approximately 5 minutes on each side, or until cooked through.
Meanwhile, melt the butter in a separate skillet over medium heat and add the diced onion. Cook for about 3 minutes, stirring occasionally. Add the bacon and cook for an additional 5 minutes, stirring occasionally.
To assemble, place the patties on the hamburger buns. Top each patty with a slice of cheese, and then the cooked onions and bacon. Add salt and pepper to taste.
Enjoy!
