Flax meal is healthy.
Flax meal is easy to make in your Blendtec.
(I assume any other high-end blender would work similarly.)
Fill to just about covering the blades with Flax Seed.
(I prefer Golden Flax Seed. And buy it in bulk from Wheat Monatana
when I do a large group order annually from the warehouse.)
Turn on blender Speed 1 to 3. Let run full cycle.
If you still see whole seeds.
Run a second time.
Store in your refrigerator until using.
I like to have a pint-sized mason jar full, ready to use.
It takes several batches to fill the jar, but that way it doesn't heat up
while grinding/blending for a long period of time.
