I've been growing some shiso in my Aerogarden - http://i.imgur.com/zitLRIV.jpg http://i.imgur.com/zitLRIV.jpg - and it's to the point that I have to replant it due to rampant growth crowding out half the other plants after I already pruned what you see there. Herbs are easiest I think. Mint is super low maintenance and nice for flavoring water and for cocktails. Thai basil can be tasty, and other varieties of basil are also fun. I've had no luck at all with thyme, but... eh. I'm also growing lavender just because it smells good. Veggie-wise, you can try fast growing sprouts and microgreens, perhaps? I'm also trying my hand at some bird's eye chilies despite lack of temperature control and general warm weather in SF.
