I don't have any experience with quinoa, but I've been hearing very, very good things about it. Gluten-free, a complete protein, supposedly it's good for blood-sugar as well, but double-check. It acts like rice or grain but supposedly doesn't have the downsides of pasta or rice. They say that it needs to be rinsed and soaked for a time, but that's "inactive prep" phase, not something that should greatly impinge upon your too-busy days.
