Grains are great generally. Quinoa (pronounced Keenwa) cooks very quickly and is one of the most nutritious grains you can buy (check out Holland and Barratt and other health food shops). Although it's not very flavourful (nothing that some herbs etc can't fix) it's great to bulk up other things. If you want to add some goodness to what you're eating, buy yourself some packs of seeds and nuts, bung them in the food processor (watch the sesame seeds because they go a bit gloopy when chopped) which reduces the volume but gives you a nutricious add in to porridge in the morning, pastas, grain dishes etc.
I love it!
