I stored mostly canned food and plastic spoons.
You don't need heat. You don't need water. You don't need clean dishes. Just open and eat. And it doesn't go bad for years.
I bought extra can openers too.
I tried to focus on protein so chili, beans, stew, tuna, vienna sausage.
You can live just fine for the rest of your life never eating another carb.
Without protein you die.
Protein and fat fill you up and keep you full much longer too.
A spoonful of peanut butter can go a long way so I bought a few jars.
Also, when rationing, it's better to fast and feast.
No food for a day or two and then feast.
That's much easier and healthier than eating a little each day.
