Shape meat into a patty. Sprinkle lightly with salt. TIP: You can freeze it for a few minutes if necessary to help it hold its shape.
Fire up your grill or stove top.
Cut the bacon strips in half crosswise. Cook in a skillet, flipping every couple of minutes, until crispy and well done. Transfer to a paper towel-lined plate to drain.
Place the patty on the grill and cook to desired doneness.
Toast the bun halves on an upper grill rack for 30 seconds to one minute, watching them carefully.
Place the cheese on top of the burger for the last few seconds of cooking so it just begins to melt.
Assemble the burger, topping the patty with barbecue sauce before adding the onion and top half of the bun.
