Small (and I mean SMALL) container

Hello there! I have a quick question for you guys, and am hoping you can all help. :-) I have a raised bed garden, made with cinderblocks. Traditionally, I've used the little squares that make up the blocks for things I don't care about. Flowers, mostly. However, this year I'd like to actually use them to potentially produce something useful! In the past, I've grown onion and leeks in those little squares quite nicely (with the added bonus of thier being naturally bug repellant), but I'm kind of bored with just those. Does anyone have any suggestions as to what might do decently well in the opening of a cinderblock in Arizona that is a spring/summer crop? I was thinking perhaps basil or beans? Thanks again!
