Deer season is coming up very soon in several areas, and it goes throughout the rest of the year!
For myself, we've just acquired 100 acres and so I have quite elaborate plans both for ourselves and to sell which I won't bore everyone with.
I agree with @GooseGang, people tend to grow veg and neglect staples, you can live on potatoes, you can't live on lettuce.
Previously we have grown chickpeas which are versatile and easy to grow and also nitrogen fixing. 4 bed rotation systems and square foot gardening have worked for us in the past at being quite productive in smaller spaces.
Also potato bags, I love potato bags!
Potatoes, pintos, so many options.
Lentils are another good option. I believe they're nitrogen fixers too
I go with more hardy food options (ie: potatoes, onions, carrots) that don’t need refrigeration. Fresh herbs can be dried for long lasting tea or spice ingredients. Also just for the ease of cooking basic dishes that can be made into a variety of things (boiled chicken, mashed potatoes, baked beans) are helpful to have and use as well.
