Preheat the oven to 400.
Cook bag of frozen cauliflower rice for 4 minutes in the microwave or on the stovetop, allow to sit for one minute to cool.
Using a nut bag or a dish cloth, squeeze the water out of the steamed cauliflower rice until it is very dry.
In a bowl of a food processor*, add cauliflower, eggs, salt, yogurt, almond flour, and arrowroot.
Blend until very smooth. It will be very much like batter and this is what you want.
On a parchment lined baking sheet, put ½ cup batter and using a spatula or the back of a spoon, create an 8 inch circle of batter.
Bake the crust for 6 minutes until it is firm but not brown. This is just a pre-bake to get the crust firm enough for toppings.
Remove crust from the oven and turn the heat up to 500.
Top your pizza crust and bake for about 15-18 minutes or until cheese is melted, golden and bubbly.
Enjoy!
