Notes

  • There is no need to drain the beef unless you find it has too much excess grease. If you do drain it, make sure to do so before seasoning, so no flavor is lost.
  • I enjoy shredded cheddar the most with this dish, but you can use any cheese that melts well, like Colby Jack, Monterey Jack Cheese, or a Mexican shredded cheese blend.
