Great idea! We will be doing a lunch in a couple of weeks that is entirely shelf stable, and might do a whole episode in future on shelf stable meals!

Cool! I look forward to it.
A thing we found helpful in cutting costs in our household is dried beans. They're cheaper, last longer on the shelf, taste better, and if you have a pressure cooker it's almost no extra work. It takes about an hour cook time, but it's only a couple of minutes of touch time to dump in beans, water, and spices.
The InstantPot was well worth the investment for us. We ended up buying a second (larger) one after we used the first one for a few months. 5/5, would recommend!
