Tapioca and Cheese Pizza Crust with Mozzarella and Pesto

"This addicting gluten-free pizza crust recipe is crispy on the outside and soft & chewy on the inside (also: filled with cheese!) Inspired by Brazilian cheese bread, this tapioca and cheese crust is so easy you can have dinner on the table in an hour even while juggling a toddler and a newborn. What toppings will you choose?"
