any vegan thats been vegan for 30+ years

i would not suggest a pure vegan diet for longer than 3 months - not unless you are a nutritionist (most people have no clue).

on the other hand, eggs for breaky once a week is entirely sufficient.

You salt or smoke meat and fish and it lasts for weeks/months.

• smoked meat lasts for 4 days

• cured chicken lasts up to 2 weeks in the refrigerator

you might want to start rethinking your strategy, mate - seems you have underestimated the importance of a deep freezer in the process of preserving meats.
