Make the Burgers: Mix all the ingredients together with your hands, except the oil, in a bowl.

Divide the meat mixture into 4 or 5 equal-sized patties.

Heat the oil in a large skillet over medium-high heat. Working in batches, cook the burgers, turning once, until lightly browned and cooked through, about 7 minutes per side.(A instant-read thermometer inserted in the center of the thickest burger should read at least 165 degrees F.)
