Preheat oven to 475°.

Bring wine, oil, kosher salt, juice, red pepper flakes, sugar, bay leaf, and 8 cups water to a boil in a large pot. Add cauliflower, reduce heat, and simmer, turning occasionally, until a knife easily inserts into center, 15-20 minutes.

Using 2 slotted spoons or a mesh spider, transfer cauliflower to a rimmed baking sheet, draining well. Roast, rotating sheet halfway through, until brown all over, 30-40 minutes.

Serve with the Roasted Red Pepper Goat Cheese Sauce drizzled on top.

In a blender or food processor, combine the olive oil roasted red bell peppers, garlic, salt, red pepper flakes, pepper, and vinegar. Blend for 1-2 minutes until the ingredients become smooth. Add the goat cheese and blend for another minute until smooth. Taste and adjust seasonings as needed.
