My version is a pound of ground American Bison, 90/10, 8 slices of lean bacon, and sharp cheddar cheese.
Put the bacon on a plate, cover with another plate, microwave until the bacon is real crisp. take the bacon out of the plate and cool the bacon and fat.
When the fat has cooled a bit, mix it into the ground meat, crumble the bacon and mix it in.
Make your patties, put a big hunka cheese on a patty, cover with another patty, seal the edges and grill.
Serve on a grilled pretzel or onion roll with whatever accessories you like best.
