Freezer cleaning.
You know those $2 ribeye steaks sold out of a truck in parking lots? Yeah. Now keep it in the freezer for two years. Combine that with a tiny amount of frozen salmon donated by someone a year ago and some instant mashed potatoes and corn.
I’m half asleep and this is what I get from that.
Cost per person $3.25 not including the peanut butter and jelly I will definitely eat after this.
For long term preservation of cooked food I prefer canning. Most of the stuff in the freezer is factory sealed.
I love a good food poisoning mystery and am constantly warning people in canning groups about unsafe practices. Even if it gets me banned because some groups have very strict rules about warning people they could die from doing things like water bath canning unpeeled fermented beets. True story.
