1/2 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
1 cup shredded part-skim mozzarella
1/4 cup Pizza sauce

Working in batches if needed, pulse cauliflower in a food processor, until fine crumbs form and are rice-like in texture. Transfer to a clean kitchen towel and tightly squeeze to remove as much liquid as possible.
Mix cauliflower, garlic, egg, parmesan, brown rice flour, Italian seasoning, salt, and black pepper in a medium bowl until mixture holds together when pinched.

Continue to bake until cheese melts, about 5–7 minutes. Let sit 5 minutes on wire rack before cutting
