Put the mozzarella, coconut flour, psyllium husk, egg and salt in a blender/food processor. Blend until you have a smooth dough.
Grease your hands with olive oil and form 2 dough balls.
Roll out the dough between 2 sheets of baking paper.
Bake your pizza crust for 7 minutes until slightly browned.
Remove from the oven and spread with Marinara Sauce. (see notes)
Decorate with a bit of mozzarella (parmesan would work here too), pepperoni slices and some fresh basil. Return to the oven for another 6 minutes.
I used psyllium husks, NOT psyllium husk powder. If you want to use fine psyllium husk powder, halve the amount as it's much more absorbent. The nutrition is calculated for 1 pizza. The crust alone contains 1.7 net carbs per portion.
