Split the burger patties in half horizontally, so that you essentially have two thinner burger patties. Place an equal amount of blue cheese and bacon pieces on top of one half pattie, and then place the other half back on top of it and forming it back into one pattie with the cheese and bacon being on the inside. Season the outsides with salt and pepper, and grill, or cook to desired doneness. Toast the buns and place burgers on each bun, and top with toppings of choice. When you cut or bite into the burger the cheese should be melted and creamy.
