Mountain House. Decent quality.
Yes, we have a year supply of that brand and like all freeze dried it lasts 25 years. Anymore than a year, you better be in the country with other resources. If not, you'll die if urban first and then suburban. We're suburban.
The trick is to have enough water supply so you don't have to eat it dry out of the can. Remember, you have 50 gallons of potable water in your hot water heater. Attach a short hose with a valve to your drain plug. If you live rural and have a stream/river, you will still need filters. Also, I just bought a Solar Oven (Google)that will heat/boil/cook as long as the Sun is out.
Last thought: If disaster is heading your way, fill up every bathtub and container you can before the water mains break. You also have drinkable water in your toiler tanks (suggest filtered). Get a 5 gallon tub and plastic bags to deal with your feces so you don't have to waste water for flushing.
I used to eat Mountainhouse when I went camping.
Is it gourmet? Nope. But it cooks up well and it’s eatable.
If it gets down to that, mae sure you’ve bought spices and liquor to trade.
Thank you.
