Kale?

The local farmer's market has been getting some great kale. However, I don't know of many good recipes for kale. Can anyone suggest anything? So far I've just been steaming/blanching it with any combination of balsamic vinegar, soy sauce, and olive oil. Can kale be substituted for cabbage effectively? Specifically, I'd prefer recipes with kale as the primary ingredient to be served as a side dish (as opposed to something like minestrone soup). I have lots of frozen leftovers to be eaten, so I'd like the kale to be a side dish to an already-cooked meal. I have no dietary restrictions, so the sky's the limit! (I also enjoy recipes designed for certain dietary restrictions, so please don't let that be a deterrent either ^_^)
