  Divide the ground beef mixture into 12 portions, 5 ounces each, then gently shape into patties. Season the patties on both sides with the Traeger Beef Rub.

• 4

  Arrange the patties directly on the grill grates. Close the lid and cook for 4 minutes, then flip and cook for 2 minutes longer. Top each patty with a slice of cheese, close the lid again, and cook until the cheese is melted, 2 minutes more. During the last minute of cooking, place the buns on the grill to toast.
