Place a pizza stone or baking sheet in your oven, and preheat the oven to 450 degrees F (230 degrees C). On a pizza peel or cutting board, place a piece of parchment sprayed with Nonstick Cooking Spray (as needed).
For the crust, remove the florets from the of Cauliflower (1).
Place the florets in a food processor or blender and pulse until the cauliflower has the texture of sand. You should have about 2.5-3 cups of cauliflower sand.
Transfer the cauliflower sand to a microwave-safe bowl and heat in the Panasonic Microwave Oven covered, for 4 minutes. Let your cauliflower cool completely.
Place the cauliflower in a towel and wring it tightly. You want to remove as much moisture from the cauliflower as humanly possible. I recommend doing this in two batches to get your cauliflower really dry.
Place the cauliflower pulp in a mixing bowl and add the Parmesan Cheese (1/4 cup), Shredded Part-Skim Mozzarella Cheese (1/4 cup), Dried Oregano (1/2 teaspoon), Dried Basil (1/2 teaspoon), Crushed Red Pepper Flakes (1/4 teaspoon), Salt (1/4 teaspoon), Garlic Powder (1/2 teaspoon) and Egg (1).
Using your hands, mix until well combined.
Form the dough into a ball and place it on the parchment-lined pizza peel or cutting board.
Place a second piece of sprayed parchment on top of the dough ball and roll it out into a circle about 1/6-inch in thickness.
Remove the second sheet of parchment and briefly set your pizza aside while you prepare your vegetables.
Place the Broccoli Florets (1/3 cup), Red Bell Pepper (1/2) and Red Onion (1/4) on a foil-lined baking sheet. Drizzle with Olive Oil (2 teaspoon) and sprinkle with Salt.
Carefully transfer your dough to the hot pizza stone/baking sheet. Place your vegetables in the oven along with your dough. Bake for 8-10 minutes until the dough is golden brown. Carefully remove it from the oven.
While your dough is baking, quickly sauté the Baby Bella Mushroom (1/3 cup) in Olive Oil (1 teaspoon) for 3-4 minutes until tender. Briefly set aside.
Go ahead and take your vegetables out of the oven when the dough is finished.
Spread the Pizza Sauce (1/4 cup) over the pizza dough and sprinkle with an even layer of Shredded Part-Skim Mozzarella Cheese (1/2 cup). Top with the roasted vegetables, sautéed mushrooms, and Goat Cheese (1 ounce).
Bake for another 5-7 minutes until the cheese is melted and bubbling slightly.
Remove your pizza from the oven and let cool for 2-3 minutes before slicing to make sure that the crust stays intact. Cooking results may vary depending on microwave oven used.
