Divide into 4 portions. Form into patties, making sure to mold it enough for the meat to stick together.
Once made, form place a small thumbprint depression in the center of each patty to keep the hamburger from puffing up into a round ball during grilling.
Make your onion rings either a frozen packaged variety or my air fryer onion rings.
While onion rings are cooking, preheat the grill.
Grill hamburgers for about 8 minutes for medium doneness, turning halfway through. When you have a minute left to cooking add a slice of cheese to the top. When cheese is melted, remove to a platter.
If you prefer your hamburger buns toasted on the grill, when there is about 4 minutes left, slice them in half and put face down on grill. Check on them from time to time and watch them carefully as they can char rather quickly.
To serve: Place cheeseburger on the bottom of a hamburger bun, top with 3 onion rings and place lettuce and a slice of tomato on top half of the bun. Serve with your favorite barbecue sauce.
