Start preheating your waffle maker. If it has a setting, it should be on the high end.
Place all ingredients in a power blender.
Start blending on low power for a few seconds then progressively increase to max power. Blend until smooth, 30 to 45 seconds more.
Let the batter rest for 5 minutes.
If the waffle maker is not non-stick, you'll need to spray with a little canola or avocado oil.
When the waffle maker is nice and hot, carefully pour in about 7/8 cup of the batter. (At first, I was pouring from a separate cup, but now that I am familiar with the process I pour straight from the blender.)
Let the waffle cook approximately 6 minutes. (You'll have to find the exact timing based on your waffling setup but these take longer to cook than white-flour waffles.)
Carefully remove the waffle and keep warm.
Let the waffle maker return to the right temperature if needed, and repeat with another cup of batter, until you have none left.
Serve with lots of fresh fruit and a little maple syrup or, for a Dr. Greger-approved sweetener, blackstrap molasses.
