I finally tried it! I made my own cauliflower crust pizza and it turned out better than I thought. Jon gave me a recipe from Cooking Light magazine that he thought would work out well and I tried it and it was great.
I only used half a head of cauliflower for the crust (thought the recipe called for a whole head) and put that in a food processor until it was the consistency of rice. I put that on parchment paper and baked it at 375F for about 25 minutes until it was golden brown stirring once during baking. While that was in the oven I sauted about a cup of mushrooms. When the cauliflower was done I combined it with about a teaspoon of olive oil, 1/4 cup of basil, a pinch of pepper and salt, 3 cloves of minced garlic, 2 ounces of mozzarella cheese, 2 egg whites, and about a half a cup of shredded parmesan. I pressed the crust into a circle on a baking sheet lined with parchment and baked the crust at 450F for 25minutes or until it was browned. I took the pan out of the oven and topped with with my mushrooms, about half a tomato, a handful of spinach, 1/4 cup of basil, and a few slices of mozzarella. I baked it for about 10more minutes and voila! It was great. The crust held up pretty well and I think it could've been crispier if I flipped the crust while it was baking the first time to make sure more moisture was pulled from it but overall successful.
It looked just like a pizza and was almost as satisfying without all the calories. Not that I'm going to replace actual pizza with this but it was a fun substitute for the night!
