Thank you a lot! Forgot about quinoa. I have never took it as a backpacking food. At home I cook it and add some flaxseed oil. It does also contain Omega 3. You can find it only in fish, but if you are a vegetarian, flaxseed is the only source of it.
Don't know what chia is. Googled it, seems like some plant from Salvia family? We have salvia on north (where I live), but not sure about the chia you've mentioned.
