Preheat oven to 375 degrees F.
Place riced cauliflower in an oven-safe baking dish and cook 20 minutes.
Remove cauliflower from oven and let cool 10 minutes. Place cooled cauliflower in a cheese cloth or clean kitchen towel and squeeze excess water out.
Increase oven temperature to 450 degrees F.
Place cauliflower in a mixing bowl. Add eggs, ½ cup mozzarella, parmesan, minced garlic, oregano, parsley, salt, and pepper. Mix well to combine.

Bring to boil, then reduce heat and simmer 15-20 minutes.
