I've recently - yesterday, and lunch today, also for late dinner - made blinis and pancakes using egg instead of water or any other fluid in the batter. This means more with less flour, more protein and less carbs. Taste and texture a bit different, but good. No potato flour needed this way to use quinoa for blinis or pancakes when done instead of buckwheat.
EDIT: And I had them at lunch with bacon, at dinner with beef patty.
