I started out with a large head of cauliflower, then grated half which gave me about 2 cups. The recipe I found only calls for 1.5 cups of grated cauliflower so I put aside the rest.

Then I put it in the microwave for 8 minutes and added the following:
1 cup of mozzarella
3 cloves of minced garlic
1 beaten egg (make sure cauliflower has cooled a little before adding the egg or else it will scramble)
Spices: Oregano, Basil, Garlic Powder & Red Pepper Flakes
I combined all ingredients and spread it out on the bottom of a 9 inch cast iron skillet that I sprayed lightly with oil.
How it looked before baked.

I baked it at 450 degrees for appx 15 minutes, just until the edges began to brown.

While the crust was cooking I sauteed red & green peppers, onions and broccoli. When the crust was done I added 2 tablespoons of crushed tomatoes, a bit more mozzarella, the sauteed vegetables and some freshly grated Parmesan then baked for another 8 to 10 minutes.
Here is the final product.

Verdict: The texture of the crust is not at all like pizza dough however the taste is reminiscent of it. I don't know if it's the mozzarella but if you close your eyes you get a sense that you're eating pizza. It did not slice well, actually fell a part. I think I should have used a non-stick cookie sheet and maybe not overdue it with the veggies.
All in all I think it is a good alternative to regular pizza and will definitely make it again.
