Absolutely agree—keeping track of what you have is just as important as what you buy. I used to think I’d remember what was tucked in the back of the pantry, but after finding a bag of lentils from 2018… let’s just say I started a notebook and now use colored stickers for dates. “First in, first out” has saved me a bunch of waste, especially with things like boxed nut milks which love to expire quietly!
Canned meats are a smart addition, but I’d add canned salmon or sardines to the mix if you like the taste—lots of nutrients, decent shelf life. For dry staples, mylar bags with oxygen absorbers work wonders, but I haven’t bothered with vacuum sealing inside the mylars. Seems like overkill for most beans and grains, unless you live somewhere
