My first thought was sauteed corn and peppers, but I don't know if you can find fresh corn this time of year.
(Jen, I've always wanted to try that BC recipe! Oh, love the sweet potatoes fries, too. Must.make.crabcakes.)
Maybe roasted fingerling (or tiny) potatoes? Just olive oil, s&p, and fresh herbs to complement the crabcake recipe? Would some kind of a simple orzo dish work?
I know this wasn't your question, but I'm wondering about the "mixed greens underneath". Do you mean salad? I would think anything moist would cause them to get soggy, no?
