Whether you stocked up at a sale or bought time on a looming best-by date, you very likely have some ground beef in your freezer. It seems so useful, like such a good starting point for so many recipes, but when have you ever remembered to defrost frozen ground beef in advance? Then you've got to brown it or cook it through before it goes into your pasta dish, casserole or taco shell. It's not such a time-saver after all.
