One of the people in the comments stated that they replaced part of the quinoa with oats. So i measured out my quinoa and filled up the remaining cup and 1/4 cup or so with old fashioned oats.
I really liked the texture that the oats added to the bars. I think 100% quinoa might have resulted in a bar that was a bit too moist as well. The oats seemed to absorb some of the extra moisture from the quinoa, which in my opinion, was a good thing.
I thought the bars tasted the best slightly warm, but they were pretty darn good cold as well. I wasn't sure how they would keep so I stored them in the fridge to be on the safe side. The fridge also seemed to help the bars set up a bit better. They were a little on the loose and crumbly side while they were warm.
The first bite of these bars are a bit of a shock. I'm so used to quinoa in savory dishes that when I first tasted the quinoa in the bars my brain was like "Uh what on earth is this? Quinoa is supposed to be savory." Once you can get your mind synched up with your taste buds, it's hard to stop at one bar.
