I have been trying to teach vegetable gardening to people for the last 8 years and have finally given up. If you think when a disaster comes you can just throw some seeds into the ground and you will have enough vegetables to keep you alive.....then you need a reality check. It takes a lot more than that to feed even yourself for a full year....and most of the vegetables you will be eating won’t be the ones you like. Then there is the worry that if the worse happens and you have a garden you are going to have to defend it probably with your life.
I am fully resigned to the fact that in a worst case scenario, that I will live almost exclusively on zucchini and root vegetables. My wife IS a vegetable gardener. It is not in my blood.
