If you do not have a microwave, I’d recommend cooking the cauliflower first either in your oven or on the stovetop and then ricing it. Easiest would be to steam it and then ricing it.
The cauliflower should not be soggy at all after microwaving it. If however, you find that it is soggy, place it on a few paper towels and squeeze the water out of it.
Nutritional information based on 1 cup mozzarella cheese for topping. Please keep in mind that nutritional information is a rough estimate and can vary greatly based on products used.
The crust can be frozen, already baked, and just thaw it out on the counter or microwave. Or add the cheese and place it back in the oven and bake it for a few minutes until the cheese melts and browns.
