Last year I cut up sprouted potatoes and tossed them in soil and they did fine. The plants are large, though, so be prepared for 1 plant /sq ft or less.
This is a fantastic idea. We regularly donate canned/boxed goods to the local settlement house but adding garden produce will be especially appreciated.
