We are in our early to mid 80’s, and our appetites are not that big. My wife maintains her weight with about 1000-1200 calories.
She feels that we can last for a week + with what is in our standard freezer, protein wise.
Then, we keep a couple of dozen Progresso Soup cans on hand. She is satisfied with about a 1/3 of a can, and I’m fine with 2/3 of a can. We keep a couple of dozen of store brand canned beans, corn and ????, and they make a great mix with the canned soups. Just put an unopened cans of soup in the noon day sun for a couple of hours to warm up the lunch/dinner.
We keep about a dozen each of beef stock and chicken stock which require no refrig until opened.
So buy somethings like above on sale or from Costco/Amazon or your local store.
Our grocery discount store has a lot of canned goods on sale with good dating.
We are now ordering canned tuna and salmon with Olive oil.
My wife can do wonders with pasta, rice and beef stock and chicken stock.
We love Seeds of change rice mixes. 90 seconds in a microwave and my CPAP spare battery and solar charger can meet that challenge in about 1 hour of solar.
I have 2 propane tanks, and one is all ways full. One tank starts a lot charcoal for outdoor cooking on our Char-Broil Grill..
Bambis and the fat gray squirrels will donate to our needs.
We told our adult children, if they come here, they bring their food and water.
IF they need to bring their own their food and water...better bring a gun too.
