Preheat oven to 425 degrees F.
Cut out the core of cauliflower and divide the head into large chunks. Grate the cauliflower chunks with a grater and put in a microwave-safe bowl.
Microwave cauliflower crumbles on high in the microwave oven for 8 minutes until limp and soft. Remove from the oven and let cool until slightly warm.
Place crumbles in a kitchen towel or cloth napkin, gather corners, and hold over the sink. Twist the ends together and squeeze out as much moisture as possible. There will be a surprising amount of it and when done the cauliflower will resemble a dough ball!
Place cauliflower in a mixing bowl and add the egg 1 cup of shredded mozzarella or Italian blend cheese, salt, Parmesan, and Italian herbs. Mix together thoroughly.
Line two jelly roll pans or large baking sheets with parchment paper and spray the parchment liberally with nonstick spray or grease well with olive oil. The spray or oil will keep the crust from sticking – very important!
Place the cauliflower-cheese mixture on one of the sheets and pat out to a thin, even layer in either a circle or rectangle, as you prefer. Be sure to make the edges and the corners just as thick as the rest or they will burn when cooking. Use a paper towel to absorb any extra moisture and bake on the middle rack for 15 -20 minutes until the top is brown but not burned. If it doesn’t brown, broil on high for 3-4 minutes or until it does turn brown.
Remove from oven and dab with a paper towel to absorb any moisture and let cool for a couple of minutes. Then place the second baking sheet with parchment over the one with the crust and flip the crust onto the second baking sheet. Remove the parchment on top and dab to remove any excess oil or moisture.
Place crust under the broiler for 5-10 minutes until it browns, again being careful not to burn the edges. Remove when the crust is brown and solid. Let cool for a few minutes and the top with sauce, mozzarella, vegetable and/meat toppings, mozzarella, parmesan and sprinkle with dried herbs and granulated garlic, if desired.
Place under broiler for 4-5 minutes until the cheese starts to bubble and get brown spots. Remove from oven and place on a cooling rack and let settle for about 5 minutes. You can then use a regular pizza cutter to slice as you like.
