Using a food processor, pulse the cauliflower in 2 batches until it resembles fine rice, roughly 30 seconds.

Place cauliflower in a microwave safe bowl and cover with cling wrap. Microwave on HIGH for 5 minutes (Alternatively, you can also steam the cauliflower). Let cauliflower cool for 15 minutes.

Once cool enough to handle, transfer cauliflower to a clean kitchen towel. Tighly squeeze out any moisture as best you can leaving no water remaining. This will yield you best results.

Next transfer cauliflower pulp to a large bowl and add in egg, mozzarella, parmesan, garlic, oregano, salt and pepper. Stir to combine and form a soft dough.

Place a large piece of parchment on a baking tray. Place dough in the middle of the prepared pan and push out with your hands to form roughly a 12 inch circle. Top with my 5 minute pizza sauce, cheese and any of your favorite topping. 

Bake at 425°F (215°C) on the bottom shelf for roughly 20-25 minutes or until the cheese is golden brown.

Remove from oven and allow to cool for a few minutes minutes before cutting into 8 slices and serving. This crust doesnt crisp, so you will have to enjoy it using a knife and fork.
