Preheat the oven to 350 degrees F.

In a large microwave safe bowl combine the mozzarella cheese and cream cheese. Heat in 30 second increments until cheese is completely melted.

Stir the cheese so they are combined.

In a second smaller bowl combine the almond flour and baking powder. Mix the almond flour with the the melted cheeses.

When the almond flour and cheese are nearly combined add in a beaten egg white and stir well.

Using your hands, work the dough to make sure the egg white is completely worked into the dough (no streaks of egg whites visible) If the dough seems too wet just add 1 tablespoon of almond flour at a time until it feels right.

Lay the dough on a silicone baking sheet. Place a second silicone baking sheet on top and spread the dough into a thin rectangle.

Cut the rectangle into four sections. Place the cheese and ham in the triangle and fold the other section of dough over. Press the seams together.

Brush each calzone with the remaining egg white and sprinkle with seasoning.

Bake the calzones 22-25 minutes until the crust has turned golden brown.
