Like you said, Ors, I’m a big fan of prepping with food items that will have a positive impact on morale as well as nutrition. Granola bars, Millennium bars or similar might be great for a short period of time, but start to become problematic quickly, especially with picky eaters.

My mix includes some Millennium bars, some Wise freeze-dried meal packets, a few buckets of freeze-dried staples, some MREs (civilian but made by a company that sells to our armed forces) and First Strike Rations (put together at small scale commercially by a guy mirroring the military version). This is backed up by canned goods and staples that we rotate through regular use.

Notably, my family are all omnivorous and don’t have significant food allergies.
