fruit trees & perennial edible plants in general might be an option when time is very scarse. You plant them once, harvest "forever"
Discussion
I've got a fair number of perennials: strawberries, currants, cherry trees, apple trees, and asparagus, etc. I've also got some carrots, that didn't get fully harvested, that went to seed and reseeded.
perenial kales, roket, chives, aromatic plants, asparagus, edible flowers (including the wild ones). I got a degrated/overgrazed plot of land and working to regenerate the soil applying the syntropic forest garden principles ( https://agendagotsch.com/en/ ) and it's all so exciting. Good luck with your projects! :)
