Here's a link I just found for great polenta from 101 Cookbooks.
Polenta is corn, completely gluten-free.
It's easy enough to make without a recipe, but as this link points out, there are not only a multitude of great ways to serve it (a few of which she mentions) but also to cook it (crockpot!).
It can also be served with many different consistencies. I've got to try the soft one she's talking about!
Gluten-free can be tough at breakfast - here's a great solution, though you'll want to start the water boiling when you first wake up!
