Preheat oven to 350 degrees and grease a loaf pan.
Combine the three seeds in a high powered blender and blend to fine powder. Don't over-blend, or it will start to clump.
Pour the fine seed meals into the bowl of a mixer and combine with the remaining dry ingredients, mixing to combine.
Add in all the wet ingredients and mix vigorously for 1-2 minutes until thick and cohesive (takes a a bit for all the seeds and psyllium and coconut flour to absorb and activate!)
Using a spatula, scrape the dough into the prepared loaf pan, gently forming into a mounded loaf.
Bake in a preheated oven for 45-55 minutes, until just set on top.
Let cool completely for best texture and slicing....it will be a bit gooey from the psyllium when still hot.
Can be stored in airtight container on the counter for a few days, or in the fridge for about a week!
