Loaded everything myself, had a few ppl helping me with empty, for a short time, but besides that, everything on my own.
Takes about 1 hour for 500 meals, did over 70k most likely, do the math
But ofcourse, getting the veggies, picking them up, buying them, and getting meat/fish, took longer then cooking itself.
If you would have everything ready, 2 weeks is doable. But yea, meat decays.
