Preheat the oven to 425 F / 220 C.
Combine warm water, sugar, and yeast in a bowl. Set on the stovetop and let sit for 5-10 minutes.
After letting the yeast mixture sit, add the bread flour and salt and mix to combine.
Knead the dough in the bowl for 5 minutes. It will be kind of sticky!
Return the bowl to the stovetop and let the dough rise for 45 minutes.
During this rise time, assemble everything else. To start, cook your frozen cauliflower according to the package instructions.
Dice the onion.
In a pan, add the diced onion, butter, salt, and freshly cracked black pepper. Cook on medium heat until translucent.
While cooking the onion, mince the garlic cloves.
Once the onion is done cooking, add the garlic and cook until fragrant, roughly 30 seconds.
Reduce the heat to low. Add the flour and mix until evenly combined.
1/4 cup at a time, add the cream to the sauce. Stir after each addition and wait until the sauce has thickened slightly before adding more.
Add more freshly cracked pepper, as desired. Once the sauce has thickened slightly (it shouldn't be thin, but should still be able to "run" a little bit when you drag a spoon across the pan), take the sauce off of the heat.
Spread your pizza dough onto a circular pizza pan. Cook at 425 F / 220 C for 5 minutes.
Once the dough has pre-baked, top it as follows: alfredo sauce, 75% of the cheese, the frozen cauliflower, and then the remaining 25% of the cheese.
Bake at 425 F / 220 C for 15-17 minutes.
Enjoy!
