Only Buy Food That You Know You’ll Use
Easier said than done. Someone told me ages ago that grocery stores are strategically laid out so you get enticed. That always stuck with me. I think the best move would be to live near a grocery store, so you buy things as you need them.
I sort of addressed the idea that my roommate never waste because her food was all frozen. But there are all sorts of awful things that go along with preservation, packaging and keeping food cold. So, maybe that isn’t the best option!
