I started by combining 1 cup of plain lowfat kefir with 1/4 cup of chia seeds. I added some agave syrup and cinnamon to the mix to add some flavor. I would imagine any flavoring as long as it doesn't change the water content would work fine.
Though it is ready in 3 hours, i didn't eat mine until the next morning and it was excellent. Very creamy with the chia seeds popping in your mouth. This is a very nutritious breakfast that I think I will be going back to. This would be very nice with some berries on top.
