Yup, this is what I would do. It isn't possible for any bacteria or fungus to grow in a freezer. They can survive being frozen and when they thaw they can resume their growth, however, it's not like they know "oooooh, I've been cold for 12 months too long, let's grow like crazy and poison someone" Therefore, the risk of illness from these pathogens is the same whether the meat was frozen for a week or a year.
I would def. cook with it in a capacity that would compensate for any potential loss of flavor, like taco meat or whatevz.
