Quinoa is a grain. I find it in the health food section at the grocery store. It can be used in place of rice. I love making a cold salad with it. add fresh cut up veggies and a FF salad dressing and it is great. This website tells all about it

The good thing is that on Core it is a grain that doesn't count in the once a day rule like brown rice.
