Here's my theory...I try to stay as grain free as possible, but that's just how I feel. I am sure you can add some rolled oats (not instant oatmeal) if you would like. Also, maybe mash up a bunch of peas to add in there. The PB might be ok, not sure though, maybe just add 1 teaspoon.
I try to use minimal amounts of ingredients. KIS (Keep it Simple

Honestly, a bunch of mashed up peas just might do the trick for the taste(with flour, water and a tiny bit of oil)
