Pre-heat oven at 400F/200C
In a bowl mix the psyllium husk with water and let rest until it becomes gelatinous
In a large bowl mix white rice flour, brown rice flour, potato starch, baking powder, xanthan gum and salt
Create a well at the center and pour the psyllium gel, water and olive oil in it
Using a fork mix all the ingredients, trying to incorporate as much liquid to the dry ingredients, until you obtain a crumbly dough
Move the mixture to a worktop and work the dough with your hands, kneading until it's uniform and smooth
Place the dough on a piece of parchment paper dusted with white rice flour
Flour the surface of the dough ball, place another piece of parchment paper on top and roll the dough out with a rolling pin
Remove the top parchment paper and keep rolling until you obtain a half inch thick rectangle
Mix tomato sauce, oregano and table salt for the filling (save some for the topping)
Spread the tomato sauce on the dough, add the (vegan) mozzarella and roll the dough along the long side (save some cheese for the topping)
Slice the dough roll into 8 rolls and place them in a baking pan, previously greased with olive oil
Cover the pizza rolls with more sauce, mozzarella and oregano
Bake in preheated oven and enjoy still warm!
Store in the fridge and reheat in the microwave for a couple minutes to enjoy them as freshly baked
If you bring them to a picnic, keep them in an airtight container to prevent them from drying up
