Will they do sweet potatoes? That's at least somewhat better than regular! You could be sneaky and make the jambalaya from this site, it's SO GOOD! And uses caulifower instead of rice.
There's a chili recipe here too that I'm going to try (with a few tweaks, I don't like cinnamon in my chili), and I found a cabbage roll crock pot recipe that I'm doing tomorrow. That one is from sonofgrok.com, another good blog! Other than that, I'm looking forward to doing a lot of roasts in the crock pot this winter, with stewed tomatoes and carrots and things like that.
