I have read that some folks use quinoa as a substitute for oatmeal. The texture is not the same, but it can be cooked in much the same way (or kind of like rice). It makes a reasonable oatmeal substitute when sweetened for breakfast, and some use it in meatballs (or as a meat substitute). It's technically a seed, kind of iffy on the primal spectrum. I've never tried soaking oatmeal, but it gives me heartburn in its normal form. The only time I tried quinoa was in a pre-mixed package of a kind of porridge with maple syrup and cinnamon. The texture was weird to me, but it tasted pretty good.
