Pizza dough:

In a large bowl, combine flour, water, yeast, olive oil, sugar, and salt.

Use a bench scraper to bring the ingredients together until a loose, shaggy dough has formed.

Turn dough out onto generously floured countertop.

With your hands, knead until dough is smooth and elastic, about 10 minutes.

Shape the dough into a ball. Place in an oiled mixing bowl, then coat the dough in additional oil.

Cover and allow to stand in a warm place until dough has doubled in size, about 1.5 hours. While dough rises, prepare the caramelized onions.

Caramelized onions:

Add olive oil to a large frying pan and warm over low heat, then the sliced onions.

Cook over low heat for 45-60 minutes, stirring occasionally, until onions soft, fragrant, and deeply golden brown.

While onions caramelize, prepare the buffalo cauliflower.

Buffalo cauliflower:

Line a large rimmed baking sheet with parchment. Preheat oven to 400° F / 205° C.

In a small bowl, whisk hot sauce, olive oil, and lemon juice. Set aside.

In a large mixing bowl, garlic powder, onion powder, paprika, smoked paprika, chipotle chili flakes, black pepper, and kosher salt.

Add flour and whisk to combine, then add the water and whisk until no lumps or clumps of flour remain.

Add cauliflower florets and toss until completely coated in the flour-spice mixture.

Transfer coated florets to prepared tray.

Bake in preheated oven for 10 minutes. Toss with a spatula, then bake for 10 minutes more.

With a pastry brush, brush cauliflower florets with the hot sauce mixture.

Return to the oven and bake for 10 minutes. Flip with a spatula, brush with additional sauce, then bake for 10 minutes more.

Pizza dough (continued):

While cauliflower finishes baking, punch pizza dough down and allow it to rise again, about 10 minutes.

To assemble:

Raise the oven temperature to 450° F / 230° C.

Stretch pizza dough into a round, about 12-14 inches / 30-35 centimeters in diameter. Transfer to a pizza pan and use your fingertips to stretch again, until dough reaches the edges of the pan.

Spread dough with the blue cheese dressing.

Top with the sliced mozzarella cheese.

Top with the caramelized onions.

Top with buffalo cauliflower pieces. (Depending on the size of your head of cauliflower, you might have a few florets left over for snacking!)

Top with the crumbled blue cheese.

Sprinkle with half of the grated parmesan.

Bake in preheated oven for approximately 15 minutes, or until cheese is bubbly and crust is deeply golden brown.

Remove pizza from the oven. Garnish with chopped spring onions, chopped parsley, a drizzle of honey, and the remaining grated parmesan.

Serve immediately.
