I haven't updated it in awhile, but I have a freezer-storage thread here:
I have a thread over in H&F on meal prep. This got me going on the idea of freezer storage, OAMC (once-a-month-cooking), and other frozen ingredient & meal ideas: https://forums.anandtech.com/threads/fyi-hefty-makes-tv-dinner-trays-convenient-bodybuilding-meal-containers.2336038/ I recently...

My current approach is to meal-prep (cook) one meal or snack a day. Target is around 20 minutes of active time, so not a monster time commitment or anything, plus I just plan out what to make every day on a weekly basis. Typical batch results is 6 servings. This works out to around 180 servings a month, all for a little bit of prep time every day. Then I've got heat & eat meals & snacks ready to go for breakfast, lunch, dinner, and in-betweeners without having to do a huge amount of cooking or planning...just pull stuff out of the freezer!
I've been fortunate in my life to not have to experienced hunger, but the last month has definitely given me some food-insecurity anxiety as grocery store supplies have run low, which is one of the reasons I sprung for an electric wheat grinder...I can make bread, rolls, cookies, cakes, desserts, etc. using wheat kernels, which last 30 years when properly stored. I'm not super interested in being a prepper, because if the whole world goes to pot, you're going to have bigger issues than just food, but with nearly 8 billion people needing to go to work & feed their families, I think the game is more about the ability to get through these lean periods of time securely rather than the universe falling apart & society collapsing. So I don't see an "end of the world" scenario as happening, but I do things things will probably get scarce at different points in the future, and I definitely want to make sure I'm prepared to take care of myself & my family through those times, so +1 for a deep freezer!
They don't all have to be huge, either. My friend has a tiny apartment and she has one of those small chest freezers, which she uses as an additional countertop. You can fit a ton of homemade or store-bought slim TV dinner trays in it vertically for quick & easy meals!
