In a small bowl, combine your almond flour, salt, baking powder (or soda), and yeast. Mix gently.
In a microwave safe bowl, add the mozzarella and cream cheese. Place in the microwave for 60 seconds. Remove, stir gently, and then return to the microwave for another 30 seconds.
Remove the mixture from the microwave. Stir in the almond flour mixture. The dough may become thick and difficult to stir. I always mix with my hands, which WILL get pretty sticky. CAUTION: the dough will be pretty toasty!
Add in the egg and vanilla (and the ACV, if using baking SODA). Knead with hands until the mixture forms a consistent dough.
Place a sheet of parchment paper on a flat working surface. Plop the dough not the parchment paper. Place another sheet of parchment paper over the top.
Roll the dough out with a rolling pin on top of the top sheet of parchment paper. Roll to about ΒΌ inch thick. If desired, slice off parts of the top and bottom to add to the sides to create a more uniform rectangle shape of dough.
