Anyhow, when I was diagnosed with a gluten allergy I started making hamburger crust pizzas. Then I saw in here people were getting sausage crust pizzas from pizza houses.
Here is my take on it:
Flaten sausage onto a pan for the oven, as thin as possible (I just use my hands with a little water on them and squish it flat). Cook at 350F for about 30 minutes. While sausage crust is cooking sauté veggies or toppings of choice. Put a small amount of pizza sauce on top of cooked sausage crust, add pre-cooked veggies and cheese. Broil for 3-5 minutes. YUM!
