Coat hamburger patties on one side with BBQ sauce, place patties, sauce side down, on hot grill. When natural juices rise to top of patty (about 3 minutes), coat with BBQ sauce and turn. (Only turn patties once, this will insure patties will not dry out.)
Coat cooked side with BBQ sauce. Sprinkle a little salt if desired. Place a slice of cheese on each patty and then 3 half pieces of cooked bacon on top of cheese. Let cheese melt then place cooked hamburger patties on warmed hamburger buns. Serve immediately.
BBQ temp on high, cook approximately 3 minutes on each side.
