Welcome to the New Year!
Whole grains have been trendy for a number of years now. Along with barley, brown rice, oats, etc., there are recipes all around with different "new" whole grains too - like teff, amaranth, farro, etc. Quinoa (keen-wah) is a fairly new whole grain, but commonly available in stores, simple to cook with, and useable in a variety of recipes.
