Put mozzarella cheese and 2 oz of the cream cheese in a microwave-safe bowl. Microwave one minute. Stir. Microwave 30 seconds. Stir. At this point, all the cheese should be melted. Microwave 30 more seconds until uniform and gloopy (it should look like cheese fondue at this point).
Alternative stove top instructions: simply melt the cheeses over medium-low heat stirring constantly.
Mix in the egg and coconut flour. You will need to dump it onto wax paper and knead it by hand to thoroughly incorporate the ingredients or you can do this in a food processor with the dough blade.
Stir together the filling ingredients in a separate bowl.
Press the dough into a large rectangle (about 6x12) on a parchment-lined baking sheet using wet hands. Spread the filling down the center. Lift the parchment paper up and over the filling to easily cover it with dough. Cut into 12 pieces and separate.
Bake for 25-30 minutes until the sausage is fully cooked and the crust is golden.
