>he doesn't have chickens in his back yard
check your local ordinances, most places will let you have a couple of chickens before it becomes legally "agriculture."
They mostly look after themselves, and the chicken shit is great for the lawn. Free eggs, and every once in a while a nice chicken dinner.
Potato is easy as fuck to grow. You can take a store bought potato. Use an ice-cream scooper to scoop out one of the eyes, let it dry, and it will sprout into a new potato plant. As long as you save one more potato from each harvest than the last you've got a self propagating potato patch.
If you have a tomato plant one year, make sure to leave some fruit on the vine at the end of the season, they'll drop and you'll have more tomato plants the next year, and the year after that. They're fucking weeds.
Really the big trick if you want a self sufficient garden is to start ammending your soil and getting it off fertilizers. Compost, ash, piss, get some night crawlers and saturate the area.
You can make a grey water solar still with trash you can find at a construction site and some buckets. Not safe to drink, but perfect for watering plants.
If you've got more land you can farm catfish relatively easily.
If I had fuck-you money I already have my perfect off-the-grid mostly self sufficient hobbit hole designed.
