Remove the leaves and stalk from the head of cauliflower and chop the florets well.
Place the chopped cauliflower in a bowl, cover with a microwave-safe lid, and microwave for 10 minutes.
Using a fork, mash the cauliflower well. Transfer to a clean kitchen towel, and squeeze the cauliflower until there is no more excess water.
Place the mashed cauliflower back into the bowl, and add the parmesan, mozzarella, eggs, oregano, salt, pepper, ground paprika, and minced garlic. Mix well.
Line a baking sheet with parchment paper, spoon the cauliflower mixture onto the paper and press into a round form.
Bake the crust for 12 minutes at 355°F.
After baking, add your pizza sauce, vegetables, and shredded cheese. Bake the pizza at the same temperature for another 20 minutes.
