Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can't exist?

Cool question. I‘d imagine the easiest way I can at least think of is spraying it with liquid nitrogen. The challenge will be to get the nitrogen back in the bottle and keep it liquid in the meantime.
I think that'd shake out to being an air conditioner with nitrogen as the "air." You'd lose some nitrogen every use, but nitrogen is cheap.
The problem is your piece of pizza would become as brittle and sharp as ice, and likely to injure you if you handled it.
I‘m baffled our usernames only differ by one letter. My idea was, if you „sprayed“ the item from afar, it would cool the surrounding air and only ever so slightly touch that item. I don’t think this would flash freeze it. Feel free to correct me.
