Quinoa isn't a grain but a seed. Once it soaks up water it doesn't "mush" together like grains would, so I could see adding it to other things that would bind.
First thought is garbanzo flour-besan. You can make a dish very much polenta, made the same way. Besan is a very versatile bean flour.
I LOVE these kinds of questions! While searching for the besan polenta recipe I found this site:
You should try the chickpea tofu mixed with quinoa-although I have seen better laid out recipes for that. I liked the vegan mxxtballs myself.
This is a basic recipe for Socca-chickpea flour pancakes, from Vegetarian Times:
1 cup chickpea flour
2 cups water
2 Tbs. olive oil, divided
1 tsp. salt
1. Combine flour, water, 1 Tbs. olive oil, and salt in a bowl. Whisk until smooth and frothy, then let rest for at least 1 hour. The batter will retain a very wet consistency.
2. Preheat oven to 450°F. Grease a 10.5-inch pie pan with 1 Tbs. olive oil, and warm in oven for 1 minute. Remove pan from heat and gently pour in chickpea batter. Bake 45 to 60 minutes, or until the top begins to brown. To serve, let cool, then slice into wedges and season with salt and pepper to taste.
You can also make your own flour by putting chickpeas in a food processor, grinder or high speed blender. I never tried that, but now I will!
