Answer

A small veg garden   Arugula, there are many varieties
Lettuce , almost any type of lettuce will do it
Sprouts, almost any  type sprouts
Radishes, I would try all the varieties I can find
Garlic ,
Chives, leeks, onions,
Greens such as collard, mustard greens
Peanuts. Take about a month or two, best to grow in background while you grow something else on top.

That should get you started.
If I could grow indoors, under proper light, then I would grow tomatoes as well.

Hope this is enough,if not I can add more!
