Can you use Soy?
Personally, I’m stocking up on bacon. I can’t stand the stuff but it’s full of protein and a little goes a long way.
Bacon fat is what my parent’s families lived on in the depression. It really adds to the rice and beans.
I purchased large numbers of 45# buckets of wheat in nitrogen years ago. I've had to purchase rice and beans to supplement that so I would have anything at all to eat. The wheat may end up as a barter item as everyone in the household has some degree of allergic reaction to it.
