Soak grains, nuts, and seeds overnight. 

Next day, rinse the nuts and seeds. 

Add them to a blender, then add chia seeds with the first 2 cups of water mentioned in the list, and blend until smooth. 

Then, add the rest of the ingredients with the other 2 cups of water. 

The batter should not be too thick or thin. 

If it is too thick, add water until you get a pourable batter (not thin). 

If too thin, add some more oats. 

Adjust salt and agave to your liking. 

Pour batter into the waffle maker. Follow the instructions on your waffle maker.
