Pre-heat your over to 350 degrees and pre-grease your pie plate***
Combine your oatmeal, protein powder, cinnamon and psyllium husk powder in a bowl and slowly add your water or liquid of choice until the batter pourable (Should be thick, not watery thin)
Pour batter into your greased dish and bake for 15 minutes or until a toothpick comes out clean
Let the crust cool either in the pan, or cool on a wire rack
While your crust is baking, feel free to mix up the pie filling. Add the yogurt, pumpkin, protein powder and pumpkin pie spice into a bowl (recommend same bowl as crust for less cleanup) and stir until it is fully mixed.
Set in the fridge while your pie crust is cooling. Once your crust has cooled, use a spatula to place all the filling in the center of the pie crust and use the spatula to smooth it out to the edges.
Keep the finished product in the fridge until you are ready to cut and serve!
