When I first heard of the concept of substituting flour for various types of produce for a pizza crust, I was skeptical at best. How could a healthy vegetable achieve that chew and crispy texture that we have all grown up to love? Well, after some research and lots of experimenting, I was pleasantly surprised. The key to a great crust is squeezing out all the moisture in the vegetable, which in this case is cauliflower. You will be surprised how delicious this low calorie slice of pizza tastes!
