Vegetarian Cauliflower Pizza

Step 1
Place a steamer insert into a saucepan and fill with water to just below the bottom of the steamer. Bring water to a boil. Add cauliflower florets, cover, and steam until tender, 2 to 6 minutes. Allow to cool. Grate cauliflower and measure out 1 cup.

Step 2
Preheat the oven to 450 degrees F (230 degrees C). Spray a circular or rectangular metal baking pan with cooking spray.

Step 3
Combine grated cauliflower, 1/2 cup mozzarella cheese, and egg in a large bowl. Press mixture into the prepared baking pan evenly. Sprinkle with basil, parsley, oregano, fennel, and garlic powder.

Step 4
Bake in the preheated oven until lightly browned, 12 to 15 minutes. Remove crust from the oven and sprinkle with bell pepper, onion, and tomato. Top with remaining 1/4 cup of mozzarella cheese.

Step 5
Preheat the oven's broiler. Return cauliflower pizza to oven and broil until cheese has melted and crust is crispy, about 5 minutes.
