Black beans, not pork and beans, but yeah. I'll do more, too.
When talking this over, we laughed about how many of our favourite foods are exactly what we would stock up on for this kind of prep.
Lots of brown rice (keeps well) dozens of cans of beans. I've ALWAYS maniacally kept a LOT of toilet paper around, buy lots when it's on sale.
We also have 'outdoor freezer space' for a few more weeks.
Tero, I wish you enough leisure time today, that you can go enjoy a couple hours of your favourite cardio. (birding? Biking? Fapping? )
