Not exactly a vegetable, but making your own beer is cost effective, and tastes great (Though it will turn you into a beer snob). It costs around $100-$200 upfront investment, and then about $50 to make 5 gallons. The time cost isn't that bad either, 3 hours on the first day, then 15 minutes, once a week for three weeks.
