I'm not a prepper... but I wonder, what non-perishable items should I be stockpiling?

29. buy more of whatever non-perishable items you already enjoy & rotate it out

I made the classic beginner's prepping mistake during TFG's first term: I bought non-perishables I don't know how to cook.

You want to stock up on stuff you actually know how to work with. For example, I enjoy tuna, so I just buy more tuna. I enjoy frozen vegetables, so I just buy more. All my favorite peas and beans and rice I keep an extra bag on hand.

With this technique, you just have a month or so reserve of stuff you use all the time. There is nothing to learn. No habits to change other than buy more of what you already buy and rotate to keep it fresh.
