Depends on the season and how good they are at gardening, but a light to decent much vegetables

Let a friend or family member tend to a garden in your stead. You can probably even get an allotment, there’s typically lotteries in community gardens and putting your name forward can up the chances and in exchange you can get some veggies.

I think the point is to steward land in common, pretty sure most disabled people know some people who are able-bodied. Maybe open your yard to them
