Steps
1. Preheat your oven to 425°F (220°C).
2. In a mixing bowl, combine the cauliflower rice, mozzarella cheese, Parmesan cheese, egg, garlic powder, Italian seasoning, salt, and pepper. Mix until well combined.
3. Spread the cauliflower mixture onto a baking sheet lined with parchment paper, forming a pizza crust shape.
4. Bake the crust for 15-20 minutes, or until golden brown and firm.
5. Remove the crust from the oven and spread the marinara sauce evenly over it.
6. Top with shredded chicken, bell peppers, and spinach.
7. Return the pizza to the oven and bake for an additional 10-12 minutes, or until the toppings are heated through.
8. Remove from the oven, garnish with fresh basil leaves, slice, and enjoy your low-carb pizza!
