slave gardens

I was thinking about how many people have a full time job and how hard it is to grow there own food with the lack of time,
and it hit me that this has been done before in history, the slaves had to work all day and only got evenings and sundays to work on the garden they had,
so being that it is an almost identical situation, what they grew then will likely work for us now, just seems they had likely figured it out for us already (history is neat that way), or at least it is worth looking at to see if it gives us any good ideas given that the situation is almost identical.

they were often given poor land with rocks in it and on hill sides being that the good land was all used by the masters, and now we just cant afford it (it is just changed to economic methods and not forced direct like it was before)

most were easy to grow plants with high output and high food value, root crops seemed popular

but I should just let you read about it on the websites that do a better job than me
there are quite a few links that I found that are good
