Freezing cheese

Many years ago, a friend told me about freezing cheese for recipes (thanks, Cathy!). But it never occurred to me to do this with shredded cheese. It's usually more expensive than blocks of cheese, but for things like pizza, lasagne or other baked pasta dishes, or Mexican food like enchiladas, it saves a lot of time (both cooking, and cleaning out the food processor).

If you're lucky enough to find shredded cheese on sale when you need it for cooking, that's great. But buying in bulk sizes (Costco sells 5-lb. bags of shredded Mozzarella for $11), dividing it into smaller packages, and keeping it in the freezer for future use… it just seems like a good thing to try.
