Well, millet is probably the most alkaline grain. It's funny though--sometimes an alkaline food can cause an acid reaction. Talk about pellets that cause spasms!
Try quinoa when you're up to being experimental. I'm okay with it--just lazy at the moment. I know what you mean, though, about needing "different." Maybe rice noodles? A nice fragrant jasmine rice with something? How about organic rice noodle soup. (Imagine Asian Style Chicken Broth is fabulous)
