Place almonds in a food processor, and process until chunky. Pour into a large
bowl. Repeat this process with the pecans, sunflowers seeds, and add buckwheat into the bowl. In the empty food processor, place the cinnamon, vanilla and agave, and process until well-mixed. Add to the bowl of nuts and seeds and mix well.
Spread the mixture on to teflex sheets, and dehydrate at 145 degrees for 3 hours, and then at 105 degrees for 10Hours, or until crispy. Cool and store in a airtight glass container. It will last up to 3 months.
