Preheat oven to 380 F.
Divide the ground beef into 3 equally sized patties. Season well with salt and pepper.
Place bacon slices on a baking sheet lined with aluminum foil. Bake for 40 minutes, flipping once, until done but not overly crispy. Remove to a paper towel-lined plate to drain.
Fire up your grill and cook the burgers until the desired doneness is reached.
Toast the buns if desired.
Top patties with cheese and melt.
Slather the buns with the sauce. Add the patties, lettuce, tomato, red onion and cooked bacon.
