Start by rinsing the cauliflower florets thoroughly and patting them dry with a clean towel. Using a food processor, pulse the florets until they resemble fine crumbs.

Transfer the cauliflower rice to a microwave-safe bowl and microwave it on high for 5-6 minutes until it becomes tender. Allow it to cool slightly, then squeeze out excess moisture using a clean kitchen towel.

In a large mixing bowl, combine the well-drained cauliflower rice with one beaten egg, cream cheese, grated Parmesan, Italian seasoning, and salt. Mix until a dough-like consistency forms.

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and spread the cauliflower mixture into a thin layer about ¼ inch thick. Bake for 20-25 minutes, or until golden brown and crispy.

Once the crust is baked, let it cool for a minute. Spread pizza sauce on top, sprinkle mozzarella, and add desired toppings.

Return the pizza to the oven and bake for an additional 5-7 minutes until the cheese is melted and bubbly. Let cool before slicing.
