Stir in the cheese until melted, then pour in the half and half and stir until well blended. (I leave off the heat to prevent the potatoes from burning on the bottom, but if you find they're not hot enough, use low heat but keep stirring to prevent them from sticking.) Stir in the chipotle chile then taste and add more salt and pepper if desired.
If you prefer more vegetables with your meat, a cup of peas, corn, and/or black beans can be added to the beef, as well. I prefer to use 90% lean ground beef to keep the grease to a minimum. If you find that there is too much grease still, however, you may drain off some of the fat.
