I make a muffin similar to that with almond butter (not quite a quarter cup) and for the starchy part, either sweet potato, banana or pumpkin. It's delicious, but I consider it dessert, not a meal replacement.
I fed some to my pet bird the other day and she ate it with her back to me (how they eat when they like something so much they want to be left alone). I might start making up various concoctions of this muffin as a meal for my birds.
