Preheat oven to 375 degrees F.
Throw your cauliflower florets and pulse in a chopper until you get the consistency of rice.
Add parchment paper to a sheet pan and pour your cauliflower rice on top. Bake for about 15 minutes. (Mix the cauliflower at the halfway point to evenly cook)
When the cauliflower is done cooking, add it to another bowl so it cools off faster. Save the sheet pan.
In another bowl, whisk together your egg, dry oregano, dry basil, garlic powder, crushed red pepper flakes, and salt/black pepper per taste.
When the cauliflower is cool enough to touch, scoop it on to a cheese cloth and squeeze out as much liquid as possible. You may need to do this 1 cup at a time, and you may find yourself doing a couple rounds of this.
At this point, turn your oven back up to 450 degrees F.
Add the squeezed cauliflower to your bowl with the egg along with half of the parmesan cheese.
Mix with your hands until you form a dough-like ball.
Grab your sheet pan again and line it with a new piece of parchment paper. Add some cooking spray or a little bit of oil all over it.
Take your “dough” and use your fingers to evenly spread it all around the pan. It should look uncooked pizza dough at the end of this process.
Pop it into the oven for about 10 minutes on each side.
The crush should be golden brown and ready for toppings. If you want it crispier, you can keep it in for longer.
Add all of your toppings and pop it back into the oven for 7-10 minutes, or until your cheese is melted.
Cut into 8 slices and enjoy!
