There's a flaked quinoa hot cereal available that ought to be pretty quick cooking. Microwaving grains doesn't decrease cooking times, because water has to penetrate the dried seeds.

Really, the 20-minute stovetop cooking time for quinoa is less than what it takes to prepare the rest of a meal - just start the quinoa before you start chopping veggies, the same as you would for rice or any other grain. But Lorna Sass (pretty much my favorite cookbook author) has several pressure cooker recipes with a 12-minute total cooking time.
