Slice and dehydrated some!

Dehydrated mushies can be kept (long shelf life) to add to meals. Or put them through a food processor to make a powder (takes up much less space, if that’s an issue for you) which is great for extra flavour in soups, sauces, casseroles, etc.

You can boil them to extend shelf life. Once a food is cooked, you have another week (approximately) to use it before it goes off - maybe a little longer for eggs still in unbroken shells. Boil them, store them in the fridge, and add them to meals over the next week.

If you already have the cheese on hand, do an experiment. Cut off a piece and freeze it overnight. Next day, defrost it and see how it is. Because the issue you’re concerned about is change to texture or taste after freezing and thawing, you only need to leave it long enough to be fully frozen through - not as long as you normally would for storage.

(You wouldn’t want to buy a bulk size piece of meat/cheese just to experiment, but if you already have some on hand it’s worth trying for yourself to find out if you’ll find the result satisfactory.)
