In a medium size mixing bowl, mix coconut flour , shredded coconut, tapioca starch, baking soda and salt.
In a separate larger bowl, combine sausage with eggs, maple syrup and vanilla. Using the back of a heavy spoon or a fork, mash everything together very well.
Add the dry ingredient mixture to the bowl with the sausage mixture. Using a heavy spoon or your hands, combine everything together until the mixture becomes dough-like. Gently fold in frozen blueberries to the dough.
