Step 1

Coat a large ovenproof skillet with cooking spray. Heat the pan over medium heat. Cook the onion and garlic, stirring occasionally, until softened, about 5 minutes. Add the sausage and cook, stirring, until lightly browned, about 3 minutes. Add the rice, salt, black pepper, and 3 cups stock; bring to a boil. Reduce the heat to medium-low, and cook, stirring occasionally, until the rice is almost tender, about 30 minutes. Stir in the cauliflower; cover and cook until the cauliflower and rice are tender, about 5 minutes.

Step 2

Preheat the broiler to high. In a small bowl, whisk the flour and remaining 1/2 cup stock. Stir the stock mixture into the rice mixture. Increase the heat to medium-high and bring to a boil; cook until the sauce thickens, about 2 minutes.

Step 3

Sprinkle the cheese over the rice mixture. Broil until the cheese melts, 1 to 2 minutes. Garnish with the parsley, if desired.
