2 tablespoons sunflower seed oil (sub with ghee or butter)
In a large bowl, use your hands to mix together all of the ingredients (except the sunflower seed oil).
Take about 1/4 cup of the ground beef mix between your hands and form into a disc-shape patty. Set on a plate and repeat with all of the ground beef.
Heat the sunflower seed oil (ghee or butter) in a cast iron skillet or large pan over high heat.
When the oil begins to smoke lightly and shimmer, add the burgers, spaced about 1 inch apart. Cook the burgers until browned and slightly charred on one side (about 3-4 minutes) and then flip and repeat on the second side for the same amount of time. The burger will be medium rare. To continue cooking for medium-well and well, cover the pan with a lid and reduce the heat to medium. Cook for another 3-4 minutes on the same side.
If adding cheese, top while the burgers are still in the pan, and cover for 1 minute. Serve on your favorite bread, with any garnishes you wish: sauerkraut and swiss anyone?
