Preheat oven to 425 degrees.
Line baking sheet with parchment paper.
Prepare fat head dough by melting mozzarella cheese in microwave in 30 second intervals until very stretchy.
Add almond flour and baking powder and use a wooden spoon to mix into the melted cheese.
Crack egg into mixture and continue stirring with spoon until completely combined.
Turn the dough onto a piece of parchment paper and knead with your hands until it is uniform in color. There should not be white or yellow bits.
Divide dough into 2 equal parts. Roll each piece out into rectangles of similar size.
Place one rectangle on the baking sheet. Bake 8 minutes. Remove from oven and set aside.
Cook sausage in a skillet over MED-HIGH heat. Crumble with wooden spoon as it’s cooking. Remove from heat and drain grease.
Add cream cheese to sausage and stir until it is melted and the mixture is creamy. You may put the skillet back on the stove over low heat if needed.
Spread the sausage mixture on top of the baked layer of dough.
Add top layer of dough. Pinch edges together to seal. Poke holes in the top layer of dough to let steam escape.
Bake 8-10 minutes until top is golden brown. Let cool 5 minutes before cutting.
